Subject: [PATCH 84/84] wifi: ath11k: Allow ath11k to boot without caldata in
|
||
|
|
ftm mode
|
||
|
|
|
||
|
|
Currently, if ath11k is unable to load the calibration data file it will
|
||
|
|
always exit. However the calibration data may not be present in factory
|
||
|
|
test mode, so update the logic to allow the driver to execute in FTM mode
|
||
|
|
even if downloading the calibration data fails.
|
||
|
|
|
||
|
|
Tested-on : IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
