Subject: media: venus: dec: Handle the case where find_format fails Author: Bryan O'Donoghue bryan.odonoghue@linaro.org Date: Tue Jul 26 04:14:54 2022 +0200
Debugging the decoder on msm8916 I noticed the vdec probe was crashing if the fmt pointer was NULL.
A similar fix from Colin Ian King found by Coverity was implemented for the encoder. Implement the same fix on the decoder.
