Move comparison before the strcmp() in this if statement, and slightly
increase efficiency by not making the strcmp() each time the if gets
evaluated but only when the comparison is true.
This was suggested in a review comment.

When doing the following command:
# echo ":mod:kvm_intel" > /sys/kernel/tracing/stack_trace_filter
it triggered a crash.
This happened with the clean up of probes. It required all callers to the
regex function (doing ftrace filtering) to have ops->private be a pointer to
a trace_array. But for the stack tracer, that is not the case.
Allow for the ops->private to be NULL, and change the function command
callbacks to handle the trace_array pointer being NULL as well.

The USB core and sysfs will attempt to enumerate certain parameters
which are unsupported by the au0828 - causing inconsistent behavior
and sometimes causing the chip to reset. Avoid making these calls.
This problem manifested as intermittent cases where the au8522 would
be reset on analog video startup, in particular when starting up ALSA
audio streaming in parallel - the sysfs entries created by
snd-usb-audio on streaming startup would result in unsupported control
messages being sent during tuning which would put the chip into an
unknown state.

connect handlers
Verify that the caller-provided sockaddr structure is large enough to
contain the sa_family field, before accessing it in bind() and connect()
handlers of the Bluetooth sockets. Since neither syscall enforces a minimum
size of the corresponding memory region, very short sockaddrs (zero or one
byte long) result in operating on uninitialized memory while referencing
sa_family.

Bluetooth hci uses ordered HIGHPRI, MEM_RECLAIM workqueues. It's

According to Whiskey Cove PMIC GPIO controller specification, for GPIO
pins 0-12, GPIO input and output register control address range from,
0x4e44-0x4e50 for GPIO outputs control register
0x4e51-0x4e5d for GPIO input control register
But, currently when calculating the GPIO register offsets in to_reg()
function, all GPIO pins in the same bank uses the same GPIO control
register address. This logic is incorrect. This patch fixes this
issue.
This patch also adds support to selectively skip register modification
for virtual GPIOs.
In case of Whiskey Cove PMIC, ACPI code may use up 94 virtual GPIOs.
These virtual GPIOs are used by the ACPI code as means to access various
non GPIO bits of PMIC. So for these virtual GPIOs, we don't need to
manipulate the physical GPIO pin register. A similar patch has been
merged recently by Hans for Crystal Cove PMIC GPIO driver. You can
find more details about it in Commit 9a752b4c9ab9 ("gpio: crystalcove:
Do not write regular gpio registers for virtual GPIOs")

Here both variables 'cpu_id' and 'entry_point' are read via
read[lq]_relaxed(), from a little-endian annotated pointer
and then used as a native endian value.
This is correct since the read[lq]() family of function
internally do a little-to-native endian conversion.
But in this case, it is wrong to declare these variable as
little-endian since there are native ones.
Fix this by changing the declaration of these variables
as 'u32' or 'u64' instead of '__le32' / '__le64'.

Here the entrypoint, declared as a 64 bit integer, is read from
a pointer to 64bit integer but the read is done via readl_relaxed()
which is for 32bit quantities.
All the high bits will thus be lost which change the meaning
of the test against zero done later.
Fix this by using readq_relaxed() instead as it should be for
64bit quantities.

When hostapd adds a station, it does so before sending the association
response frame, so that it can indicate the correct status code in the
response.
However, when this then fails, or the association response already is
a reject for some other reason, then there's no station entry and thus
no per-station management queue to send the response on and it must be
sent on the probe response queue. The code should therefore not warn.
In theory, we could check and warn if the status code is success, but
that seems excessive, so just relax the check to allow any association
response frames.

If the first frame on a given TID is received with seqno 0 and needed
to be retransmitted, we erroneously drop it because the deduplication
data is initialized to zero, and then comparing
if (unlikely(ieee80211_has_retry(hdr->frame_control) &&
dup_data->last_seq[tid] == hdr->seq_ctrl &&
dup_data->last_sub_frame[tid] >= sub_frame_idx))
return true;
will return in iwl_mvm_is_dup() since last_sub_frame is also set to
zero, and sub_frame_idx is usually zero since this only covers the
relatively rare case of A-MSDU.
Fix this by initializing the last_seq array to 0xffff, which is an
impossible value for hdr->seq_ctrl to have here because the lower
four bits are the fragment number, and fragments aren't handled in
this code but go to mac80211 instead.
