Currently the exit return path when sme->key_idx >= NUM_WEPKEYS is via
label 'exit' and this checks if result is non-zero, however result has
not been initialized and contains garbage. Fix this by replacing the
goto with a return with the error code.

Pull staging/IIO driver fixes from Greg KH:
"Here are some staging and IIO driver fixes for 5.4-rc3.
The "biggest" thing here is a removal of the fbtft device and flexfb
code as they have been abandoned by their authors and are no longer
needed for that hardware.
Other than that, the usual amount of staging driver and iio driver
fixes for reported issues, and some speakup sysfs file documentation,
which has been long awaited for.
All have been in linux-next with no reported issues"

In vt6655_probe, if vnt_init() fails the cleanup code needs to be called
like other error handling cases. The call to device_free_info() is
added.

Fix mount failed "Cannot allocate memory".
When the memory gets fragmented, kzalloc() might fail to allocate
physically contiguous pages for the struct exfat_sb_info (its size is
about 34KiB) even the total free memory is enough.
Use kvzalloc() to solve this problem.

In fbtft_framebuffer_alloc the error handling path should take care of
releasing frame buffer after it is allocated via framebuffer_alloc, too.
Therefore, in two failure cases the goto destination is changed to
address this issue.

commit 174e23810cd31
("sk_buff: drop all skb extensions on free and skb scrubbing") made napi
recycle always drop skb extensions. The additional skb_ext_del() that is
performed via nf_reset on napi skb recycle is not needed anymore.
Most nf_reset() calls in the stack are there so queued skb won't block
'rmmod nf_conntrack' indefinitely.
This removes the skb_ext_del from nf_reset, and renames it to a more
fitting nf_reset_ct().
In a few selected places, add a call to skb_ext_reset to make sure that
no active extensions remain.
I am submitting this for "net", because we're still early in the release
cycle. The patch applies to net-next too, but I think the rename causes
needless divergence between those trees.

It's incorrect to compare HighestRate with 0x0b twice in the following
manner "if (HighestRate > 0x0b) ... else if (HighestRate > 0x0b) ...". The
"else if" branch is constantly false. The second comparision should be
with 0x03 according to the max_rate_idx in ODM_RAInfo_Init().

If kzalloc() returns NULL, the error path doesn't stop the flow of
control from entering rtw_hal_read_chip_version() which dereferences the
null pointer. Fix this by adding a 'goto' to the error path to more
gracefully handle the issue and avoid proceeding with initialization
steps that we're no longer prepared to handle.
Also update the debug message to be more consistent with the other debug
messages in this function.

The PCM draining behavior got broken since the recent refactoring, and
this turned out to be the incorrect expectation of the firmware
behavior regarding "draining". While I expected the "drain" flag at
the stop operation would do processing the queued samples, it seems
rather dropping the samples.
As a quick fix, just drop the SNDRV_PCM_INFO_DRAIN_TRIGGER flag, so
that the driver uses the normal PCM draining procedure. Also, put
some caution comment to the function for future readers not to fall
into the same pitfall.

Commit c440eee1a7a1 ("Staging: fbtft: Switch to the gpio descriptor
interface") removed the gpio code from fbtft_device rendering it useless.
fbtft_device is a module that was used on the Raspberry Pi to dynamically
add fbtft devices when the Pi didn't have Device Tree support.
Just remove the module since it's the responsibility of Device Tree, ACPI
or platform code to add devices.

Commit c440eee1a7a1 ("Staging: fbtft: Switch to the gpio descriptor

fbtft will now only work with Device Tree so set the dependency.
This also prevents a NULL pointer deref on non-DT platform because
fbtftops.request_gpios is not set in that case anymore.

Fix this by replacing casts to "u64" by casts to "uintptr_t", which is
either 32-bit or 64-bit, and adding an intermediate cast to "uintptr_t"
where needed.

- Consolidate hrtimer_init() + hrtimer_init_sleeper() calls into a
single function
- Implement the separation of hrtimers to be forced to expire in hard
interrupt context even when PREEMPT_RT is enabled and mark the
affected timers accordingly.
- Implement a mechanism for hrtimers and the timer wheel to protect
RT against priority inversion and live lock issues when a (hr)timer
which should be canceled is currently executing the callback.
Instead of infinitely spinning, the task which tries to cancel the
timer blocks on a per cpu base expiry lock which is held and
released by the (hr)timer expiry code.

strcpy was used multiple times in strcpy to write into dev->name.
I replaced them with strscpy.

When the number of bytes to be printed exceeds the limit snprintf
returns the number of bytes that would have been printed (if there was
no truncation). This might cause issues, hence use scnprintf which
returns the actual number of bytes printed to buffer always

The IRQ handler(isr_bh_routine()) was called twice for each interrupt
from firmware. The data was read completely during the first call and
the second call was doing nothing.
Now changed the IRQ flag from ‘level’ to ‘edge’ trigger i.e
IRQF_TRIGGER_LOW to IRQF_TRIGGER_FALLING to avoid extra interrupt
trigger.

The variable n is being assigned a value that is never read inside
an if statement block, the assignment is redundant and can be removed.
With this removed, n is only being used for a constant loop bounds
check, so replace n with that value instead and remove n completely.
