From 8aeba427296bff6a6051686f1d139c89a0b00e4c Mon Sep 17 00:00:00 2001 From: Sowmiya Sree Elavalagan Date: Fri, 26 May 2023 12:41:07 +0300 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.
