This change make load_nls() take a const parameter, so we don't need do

[ Upstream commit 8a2278ce9c ]
The DASD device driver has a function to requeue requests to the
blocklayer.
This function is used in various cases when basic settings for the device
have to be changed like High Performance Ficon related parameters or copy
pair settings.
The functions iterates over the device->ccw_queue and also removes the
requests from the block->ccw_queue.
In case the device is started on an alias device instead of the base
device it might be removed from the block->ccw_queue without having it
canceled properly before. This might lead to a hanging device since the
request is no longer on a queue and can not be handled properly.
Fix by iterating over the block->ccw_queue instead of the
device->ccw_queue. This will take care of all blocklayer related requests
and handle them on all associated DASD devices.

If a DASD request fails an error recovery procedure (ERP) request might
be built as a copy of the original request to do error recovery.
The ERP request gets a number of retries assigned.
This number is always 256 no matter what other value might have been set
for the original request. This is not what is expected when a user
specifies a certain amount of retries for the device via sysfs.
Correctly use the number of retries of the original request for ERP
requests.

When handling an AAD interrupt, if IRQ events read failed (for example,
due to i2c "Transfer while suspended" failure, i.e. when attempting to
read it while DA7219 is suspended, which may happen due to a spurious
AAD interrupt), the events array contains garbage uninitialized values.
So instead of trying to interprete those values and doing any actions
based on them (potentially resulting in misbehavior, e.g. reporting
bogus events), refuse to handle the interrupt.

[ Upstream commit 91e292917d ]
da7219_aad_suspend() disables jack detection, which should prevent
generating new interrupts by DA7219 while suspended. However, there is a
theoretical possibility that there is a pending interrupt generated just
before suspending DA7219 and not handled yet, so the IRQ handler may
still run after DA7219 is suspended. To prevent that, wait until the
pending IRQ handling is done.
This patch arose as an attempt to fix the following I2C failure
occurring sometimes during system suspend or resume:

which indicates that the AAD IRQ handler is unexpectedly running when
DA7219 is suspended, and as a result, is trying to read data from DA7219
over I2C and is hitting the I2C driver "Transfer while suspended"
failure.
However, with this patch the above failure is still reproducible. So
this patch does not fix any real observed issue so far, but at least is
useful for confirming that the above issue is not caused by a pending
IRQ but rather looks like a DA7219 hardware issue with an IRQ
unexpectedly generated after jack detection is already disabled.

When building the boot wrapper assembly files with clang after

built:
'-prefixed' is not a recognized feature for this target (ignoring feature)
'-pcrel' is not a recognized feature for this target (ignoring feature)
While it is questionable whether or not LLVM should be emitting a
warning when passed negative versions of code generation flags when
building assembly files (since it does not emit a warning for the
altivec and vsx flags), it is easy enough to work around this by just
moving the disabled flags to BOOTCFLAGS after the assignment of
BOOTAFLAGS, so that they are not added when building assembly files.
Do so to silence the warnings.

commit cdaac8e7e5 upstream.
A syzbot stress test using a corrupted disk image reported that
mark_buffer_dirty() called from __nilfs_mark_inode_dirty() or
nilfs_palloc_commit_alloc_entry() may output a kernel warning, and can
panic if the kernel is booted with panic_on_warn.
This is because nilfs2 keeps buffer pointers in local structures for some
metadata and reuses them, but such buffers may be forcibly discarded by
nilfs_clear_dirty_page() in some critical situations.
This issue is reported to appear after commit 28a65b49eb ("nilfs2: do
not write dirty data after degenerating to read-only"), but the issue has
potentially existed before.
Fix this issue by checking the uptodate flag when attempting to reuse an
internally held buffer, and reloading the metadata instead of reusing the
buffer if the flag was lost.

commit 9baeea723c upstream.
When configuring a pin as an output pin with a value of logic 0, we
end up as having a value of logic 1 on the output pin. Setting a
logic 0 a second time (or more) after that will correctly output a
logic 0 on the output pin.
By default, all GPIO pins are configured as inputs. When we enter
sc16is7xx_gpio_direction_output() for the first time, we first set the
desired value in IOSTATE, and then we configure the pin as an output.
The datasheet states that writing to IOSTATE register will trigger a
transfer of the value to the I/O pin configured as output, so if the
pin is configured as an input, nothing will be transferred.
Therefore, set the direction first in IODIR, and then set the desired
value in IOSTATE.
This is what is done in NXP application note AN10587.

commit 2861ed4d6e upstream.
The sc16is7xx_config_rs485() function is called only for the second
port (index 1, channel B), causing initialization problems for the
first port.
For the sc16is7xx driver, port->membase and port->mapbase are not set,
and their default values are 0. And we set port->iobase to the device
index. This means that when the first device is registered using the
uart_add_one_port() function, the following values will be in the port
structure:
port->membase = 0
port->mapbase = 0
port->iobase = 0
Therefore, the function uart_configure_port() in serial_core.c will
exit early because of the following check:
/*
* If there isn't a port here, don't do anything further.
*/
if (!port->iobase && !port->mapbase && !port->membase)
return;
Typically, I2C and SPI drivers do not set port->membase and
port->mapbase.
The max310x driver sets port->membase to ~0 (all ones). By
implementing the same change in this driver, uart_configure_port() is
now correctly executed for all ports.

commit 5fadc941d0 upstream.
There have been reports of USB-audio driver spewing errors at the
probe time on a few devices like Jabra and Logitech. The suggested
fix there couldn't be applied as is, unfortunately, because it'll
likely break other devices.
But, the patch suggested an interesting point: looking at the current
init code in stream.c, one may notice that it does initialize
differently from the device setup in endpoint.c. Namely, for UAC1, we
should call snd_usb_init_pitch() and snd_usb_init_sample_rate() after
setting the interface, while the init sequence at parsing calls them
before setting the interface blindly.
This patch changes the init sequence at parsing for UAC1 (and other
devices that need a similar behavior) to be aligned with the rest of
the code, setting the interface at first. And, this fixes the
long-standing problems on a few UAC1 devices like Jabra / Logitech,
as reported, too.
