Subject: crypto: rockchip - use devm_add_action_or_reset()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=16d56963e832339fc2dff6a4afce14138fb61932;p=linux-beck.git

crypto: rockchip - use devm_add_action_or_reset()

If devm_add_action() fails we are explicitly calling the cleanup to free
the resources allocated.  Lets use the helper devm_add_action_or_reset()
and return directly in case of error, as we know that the cleanup function
has been already called by the helper if there was any error.
