From: Chris Wilson <chris.p.wilson(a)intel.com>
commit 78a033433a5ae4fee85511ee075bc9a48312c79e upstream.
If we abort driver initialisation in the middle of gt/engine discovery,
some engines will be fully setup and some not. Those incompletely setup
engines only have 'engine->release == NULL' and so will leak any of the
common objects allocated.
v2:
- Drop the destroy_pinned_context() helper for now. It's not really
worth it with just a single callsite at the moment. (Janusz)

2.34.1
From: Johannes Berg <johannes.berg(a)intel.com>
If more than 255 colocated APs exist for the set of all
APs found during 2.5/5 GHz scanning, then the 6 GHz scan
construction will loop forever since the loop variable
has type u8, which can never reach the number found when
that's bigger than 255, and is stored in a u32 variable.
Also move it into the loops to have a smaller scope.
Using a u32 there is fine, we limit the number of APs in
the scan list and each has a limit on the number of RNR
entries due to the frame size. With a limit of 1000 scan
results, a frame size upper bound of 4096 (really it's
more like ~2300) and a TBTT entry size of at least 11,
we get an upper bound for the number of ~372k, well in
the bounds of a u32.

The comment before the config of the GPLL3 PLL says that the
PLL should run at 930 MHz. In contrary to this, calculating
the frequency from the current configuration values by using
19.2 MHz as input frequency defined in 'qcs404.dtsi', it gives
921.6 MHz:
$ xo=19200000; l=48; alpha=0x0; alpha_hi=0x0
$ echo "$xo * ($((l)) + $(((alpha_hi << 32 | alpha) >> 8)) / 2^32)" | bc -l
921600000.00000000000000000000
Set 'alpha_hi' in the configuration to a value used in downstream
kernels [1][2] in order to get the correct output rate:
$ xo=19200000; l=48; alpha=0x0; alpha_hi=0x70
$ echo "$xo * ($((l)) + $(((alpha_hi << 32 | alpha) >> 8)) / 2^32)" | bc -l
930000000.00000000000000000000
The change is based on static code analysis, compile tested only.
