arm64: dts: qcom: sdm630: fix gpu_speed_bin size
Historically sdm630.dtsi has used 1 byte length for the gpu_speed_bin
cell, although it spans two bytes (offset 5, size 7 bits). It was being
accepted by the kernel because before the commit 7a06ef751077 ("nvmem:
core: fix bit offsets of more than one byte") the kernel didn't have
length check. After this commit nvmem core rejects QFPROM on sdm630 /
sdm660, making GPU and USB unusable on those platforms.
Set the size of the gpu_speed_bin cell to 2 bytes, fixing the parsing
error. While we are at it, update the length to 8 bits as pointed out by

Initializing automatic __free variables to NULL without need (e.g.
branches with different allocations), followed by actual allocation is
in contrary to explicit coding rules guiding cleanup.h:
"Given that the "__free(...) = NULL" pattern for variables defined at
the top of the function poses this potential interdependency problem the
recommendation is to always define and assign variables in one statement
and not group variable definitions at the top of the function when
__free() is used."
Code does not have a bug, but is less readable and uses discouraged
coding practice, so fix that by moving declaration to the place of
assignment.

extract the correct address from the provided bug_entry. Just do that to

perf/x86/intel: Fix NULL event dereference crash in handle_pmi_common()
handle_pmi_common() may observe an active bit set in cpuc->active_mask
while the corresponding cpuc->events[] entry has already been cleared,
which leads to a NULL pointer dereference.
This can happen when interrupt throttling stops all events in a group
while PEBS processing is still in progress. perf_event_overflow() can
trigger perf_event_throttle_group(), which stops the group and clears
the cpuc->events[] entry, but the active bit may still be set when
handle_pmi_common() iterates over the events.
The following recent fix:
7e772a93eb61 ("perf/x86: Fix NULL event access and potential PEBS record loss")
moved the cpuc->events[] clearing from x86_pmu_stop() to x86_pmu_del() and
relied on cpuc->active_mask/pebs_enabled checks. However,
handle_pmi_common() can still encounter a NULL cpuc->events[] entry
despite the active bit being set.
Add an explicit NULL check on the event pointer before using it,
to cover this legitimate scenario and avoid the NULL dereference crash.
