[ Upstream commit 564d4eceb97eaf381dd6ef6470b06377bb50c95a ]
The bug was found during fuzzing. Stacktrace locates it in
ath5k_eeprom_convert_pcal_info_5111.
When none of the curve is selected in the loop, idx can go
up to AR5K_EEPROM_N_PD_CURVES. The line makes pd out of bound.
pd = &chinfo[pier].pd_curves[idx];
There are many OOB writes using pd later in the code. So I
added a sanity check for idx. Checks for other loops involving
AR5K_EEPROM_N_PD_CURVES are not needed as the loop index is not
used outside the loops.
The patch is NOT tested with real device.
The following is the fuzzing report

[ Upstream commit 3df6d74aedfdca919cca475d15dfdbc8b05c9e5d ]
If amss.bin was missing ath11k would crash during 'rmmod ath11k_pci'. The
reason for that was that we were using mhi_async_power_up() which does not
check any errors. But mhi_sync_power_up() on the other hand does check for
errors so let's use that to fix the crash.
I was not able to find a reason why an async version was used.
ath11k_mhi_start() (which enables state ATH11K_MHI_POWER_ON) is called from
ath11k_hif_power_up(), which can sleep. So sync version should be safe to use
here.

[ Upstream commit 5666ee154f4696c011dfa8544aaf5591b6b87515 ]
When adding 6GHz channels to scan request based on reported
co-located APs, don't add channels that have only APs with
"non-transmitted" BSSes if they only match the wildcard SSID since
they will be found by probing the "transmitted" BSS.

[ Upstream commit d8d4dd26b9e0469baf5017f0544d852fd4e3fb6d ]
Currently, fragmented EBS was set for a channel only if the 'hb_type'
was set to fragmented or balanced scan. However, 'hb_type' is set only
in case of CDB, and thus fragmented EBS is never set for a channel for
non-CDB devices. Fix it.
