Subject: ASoC: amd: acp: Fix error handling in .remove()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0deb003933052ac1a44b5f94b927484be6e34f86;p=linux.git

ASoC: amd: acp: Fix error handling in .remove()

Even in the presence of problems (here: rn_acp_deinit() might fail), it's
important to unregister all resources acquired during .probe() because
even if .remove() returns an error code, the device is removed.

As .remove() is only called after .probe() returned success, platdata
must be valid, so the first check in .remove() can just be dropped.

This is a preparation for making platform remove callbacks return void.
