Subject: media: qcom: camss: Propagate vfe_reset error up the callstack
Author: Bryan O'Donoghue <bryan.odonog...@linaro.org>
Date: Mon Sep 25 16:47:06 2023 +0100
A previous patch I had removed the returns from vfe_disable() since we
didn't trap any meaningful errors. Konrad pointed out vfe_reset() could
return an error, which is true.
Trap the vfe_reset() error code and throw it up the callstack.
