[ Upstream commit 4d431153e7 ]
The BusLogic driver has build errors on ia64 due to a name collision (in
the #included FlashPoint.c file). Rename the struct field in struct
sccb_mgr_info from si_flags to si_mflags (manager flags) to mend the build.
This is the first problem. There are 50+ others after this one:

[ Upstream commit 8b0ed8443a ]
The caller of wb_get_create() should pin the memcg, because
wb_get_create() relies on this guarantee. The rcu read lock
only can guarantee that the memcg css returned by css_from_id()
cannot be released, but the reference of the memcg can be zero.
rcu_read_lock()
memcg_css = css_from_id()
wb_get_create(memcg_css)
cgwb_create(memcg_css)
// css_get can change the ref counter from 0 back to 1
css_get(memcg_css)

Fix it by holding a reference to the css before calling
wb_get_create(). This is not a problem I encountered in the
real world. Just the result of a code review.

[ Upstream commit 0de449d599 ]
As documented at drivers/base/platform.c for platform_get_irq:
* Gets an IRQ for a platform device and prints an error message if finding the
* IRQ fails. Device drivers should check the return value for errors so as to
* not pass a negative integer value to the request_irq() APIs.
So, the driver should check that platform_get_irq() return value
is _negative_, not that it's equal to zero, because -ENXIO (return
value from request_irq() if irq was not found) will
pass this check and it leads to passing negative irq to request_irq()

The snprintf() function returns the number of bytes which would have been
printed if the buffer was large enough. In other words it can return ">=
remain" but this code assumes it returns "== remain".
The run time impact of this bug is not very severe. The next iteration
through the loop would trigger a WARN() when we pass a negative limit to
snprintf(). We would then return success instead of -E2BIG.
The kernel implementation of snprintf() will never return negatives so
there is no need to check and I have deleted that dead code.

[ Upstream commit 888be6067b ]
Currently, a device description can be obtained using ACPI, if the _STR
method exists for a particular device, and then exposed to the userspace
via a sysfs object as a string value.
If the _STR method is available for a given device then the data
(usually a Unicode string) is read and stored in a buffer (of the
ACPI_TYPE_BUFFER type) with a pointer to said buffer cached in the
struct acpi_device_pnp for later access.
The description_show() function is responsible for exposing the device
description to the userspace via a corresponding sysfs object and
internally calls the utf16s_to_utf8s() function with a pointer to the
buffer that contains the Unicode string so that it can be converted from
UTF16 encoding to UTF8 and thus allowing for the value to be safely
stored and later displayed.
When invoking the utf16s_to_utf8s() function, the description_show()
function also sets a limit of the data that can be saved into a provided
buffer as a result of the character conversion to be a total of
PAGE_SIZE, and upon completion, the utf16s_to_utf8s() function returns
an integer value denoting the number of bytes that have been written
into the provided buffer.
Following the execution of the utf16s_to_utf8s() a newline character
will be added at the end of the resulting buffer so that when the value
is read in the userspace through the sysfs object then it would include
newline making it more accessible when working with the sysfs file
system in the shell, etc. Normally, this wouldn't be a problem, but if
the function utf16s_to_utf8s() happens to return the number of bytes
written to be precisely PAGE_SIZE, then we would overrun the buffer and
write the newline character outside the allotted space which can have
undefined consequences or result in a failure.
To fix this buffer overrun, ensure that there always is enough space
left for the newline character to be safely appended.

After it was removed (because the main purpose of using it, to
update the status member was itself removed) the global variable
unintenionally stood in as its replacement.

The current sun6i SPI implementation initializes the transfer too early,
resulting in SCK going high before the transfer. When using an additional
(gpio) chipselect with sun6i, the chipselect is asserted at a time when
clock is high, making the SPI transfer fail.
This is due to SUN6I_GBL_CTL_BUS_ENABLE being written into
SUN6I_GBL_CTL_REG at an early stage. Moving that to the transfer
function, hence, right before the transfer starts, mitigates that
problem.

Rename struct sms_msg_data4 to sms_msg_data5 and increase the size of

the 5th element of msg_data is being accessed in function
smscore_load_firmware_family2():
1006 trigger_msg->msg_data[4] = 4; /* Task ID */
Also, there is no need for the object _trigger_msg_ of type struct
sms_msg_data *, when _msg_ can be used, directly. Notice that msg_data
in struct sms_msg_data is a one-element array, which causes multiple
out-of-bounds warnings when accessing beyond its first element
in function smscore_load_firmware_family2():

even when enough dynamic memory is allocated for _msg_:
929 /* PAGE_SIZE buffer shall be enough and dma aligned */
930 msg = kmalloc(PAGE_SIZE, GFP_KERNEL | coredev->gfp_buf_flags);
but as _msg_ is casted to (struct sms_msg_data *):
992 struct sms_msg_data *trigger_msg =
993 (struct sms_msg_data *) msg;
the out-of-bounds warnings are actually valid and should be addressed.
Fix this by declaring object _msg_ of type struct sms_msg_data5 *,
which contains a 5-elements array, instead of just 4. And use
_msg_ directly, instead of creating object trigger_msg.

[ Upstream commit 8edcb5049a ]
The use of an enum named 'RST' conflicts with a #define macro
named 'RST' in arch/mips/include/asm/mach-rc32434/rb.h.
The MIPS use of RST was there first (AFAICT), so change the
media/i2c/ uses of RST to be named 'RSET'.
'git grep -w RSET' does not report any naming conflicts with the
new name.
This fixes multiple build errors:
arch/mips/include/asm/mach-rc32434/rb.h:15:14: error: expected identifier before '(' token
15 | #define RST (1 << 15)
| ^
drivers/media/i2c/s5c73m3/s5c73m3.h:356:2: note: in expansion of macro 'RST'
356 | RST,
| ^~~
../arch/mips/include/asm/mach-rc32434/rb.h:15:14: error: expected identifier before '(' token
15 | #define RST (1 << 15)
| ^
../drivers/media/i2c/s5k6aa.c:180:2: note: in expansion of macro 'RST'
180 | RST,

and some others that I have trimmed.
