While changing the number of interrupt channels, be2net stops adapter
operation (including netif_tx_disable()) but it doesn't signal that it
cannot transmit. This may lead dev_watchdog() to falsely trigger during
that time.
Add the missing call to netif_carrier_off(), following the pattern used in
many other drivers. netif_carrier_on() is already taken care of in
be_open().

Refactoring of axp20x driver introduced a bug in AXP803's DCDC6
regulator definition. AXP803_DCDC6_1120mV_STEPS was obtained by
subtracting 0x47 and 0x33. This should be 0x14 (hex) and not 14
(dec).
Refactoring also carried over a bug in DCDC5 regulator definition.
Number of possible voltages must be for 1 bigger than maximum valid
voltage index, because 0 is also valid and it means lowest voltage.

In DCDCD case, axp806_dcdcd_ranges[] contains two ranges with same
start and end macros, which is clearly wrong. Second range starts at
1.6V so it should use AXP806_DCDCD_1600mV_[START|END] macros. They are

The simple_strtol() function is deprecated. kstrto[l,u32]() is
the correct replacement as it can properly handle overflows.
This patch replaces the deprecated simple_strtol() use introduced recently.
As clk is of type uint32_t, we are safe to use kstrtou32().
It is also safe to return zero on string parsing error,
similar to the case of returning zero if buf is empty in parse_clk().

Some machines change the brightness themselves when a brightness hotkey
gets pressed, despite us telling them not to. This causes the brightness to
go two steps up / down when the hotkey is pressed. This is esp. a problem
on older machines with only a few brightness levels.
This commit adds a new hw_changes_brightness quirk which makes
acpi_video_device_notify() only call backlight_force_update(...,
BACKLIGHT_UPDATE_HOTKEY) and not do anything else, notifying userspace
that the brightness was changed and leaving it at that fixing the dual

GPIO fixes for v5.3-rc1
- silence error messages on probe deferral in gpio-davinci
- fix a memory leak in gpiolib-of
- fix a potential use-after-free error in gpio-em
This reverts commit fbbf145a0e.
It seems I was misguided in my fixup, which was working at the
time but did not work on the final v5.2.
The patch tried to avoid a quirk the gpiolib code not to treat
"spi-gpio" CS gpios "special" by enforcing them to be active
low, in the belief that since the "spi-gpio" driver was
parsing the device tree on its own, it did not care to inspect
the "spi-cs-high" attribute on the device nodes.
That's wrong. The SPI core was inspecting them inside the
of_spi_parse_dt() funtion and setting SPI_CS_HIGH on the
nodes, and the driver inspected this flag when driving the
line.
As of now, the core handles the GPIO and it will consistently
set the GPIO descriptor to 1 to enable CS, strictly requireing
the gpiolib to invert it. And the gpiolib should indeed
enforce active low on the CS line.
Device trees should of course put the right flag on the GPIO
handles, but it used to not matter. If we don't enforce active
low on "gpio-gpio" we may run into ABI backward compatibility
issues, so revert this.

When mlx5e_attach_encap() calls mlx5e_get_tc_tun() to get the tunnel
info data struct, check that returned value is not NULL, as would be in
the case of unsupported encapsulation.

This reverts commit 031e610a6a, reversing
changes made to 52d2d44eee.
The mm changes in there we premature and not fully ack or reviewed by core mm folks,
I dropped the ball by merging them via this tree, so lets take em all back out.

dma_alloc_coherent has already zeroed the memory.

Since commit ed194d1367 ("usb: core: remove local_irq_save() around
->complete() handler") the handler rt2x00usb_interrupt_rxdone() is
not running with interrupts disabled anymore. So this completion handler
is not guaranteed to run completely before workqueue processing starts
for the same queue entry.
Be sure to set all other flags in the entry correctly before marking
this entry ready for workqueue processing. This way we cannot miss error
conditions that need to be signalled from the completion handler to the
worker thread.
Note that rt2x00usb_work_rxdone() processes all available entries, not
only such for which queue_work() was called.
This patch is similar to what commit df71c9cfce ("rt2x00: fix order
of entry flags modification") did for TX processing.
This fixes a regression on a RT5370 based wifi stick in AP mode, which
suddenly stopped data transmission after some period of heavy load. Also
stopping the hanging hostapd resulted in the error message "ieee80211
phy0: rt2x00queue_flush_queue: Warning - Queue 14 failed to flush".
Other operation modes are probably affected as well, this just was
the used testcase.

As clang points out, the vht_pfr is assigned to a struct member
without being initialized in one case:
drivers/net/wireless/ath/ath10k/mac.c:7528:7: error: variable 'vht_pfr' is used uninitialized whenever 'if' condition
is false [-Werror,-Wsometimes-uninitialized]
if (!ath10k_mac_can_set_bitrate_mask(ar, band, mask,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/wireless/ath/ath10k/mac.c:7551:20: note: uninitialized use occurs here
arvif->vht_pfr = vht_pfr;
^~~~~~~
drivers/net/wireless/ath/ath10k/mac.c:7528:3: note: remove the 'if' if its condition is always true
if (!ath10k_mac_can_set_bitrate_mask(ar, band, mask,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/wireless/ath/ath10k/mac.c:7483:12: note: initialize the variable 'vht_pfr' to silence this warning
u8 vht_pfr;
Add an explicit but probably incorrect initialization here.
I suspect we want a better fix here, but chose this approach to
illustrate the issue.

Add support for C-step devices. Currently we don't have a nice way of
matching the step and choosing the proper configuration, so we need to
switch the config structs one by one.
