Subject: [PATCH 173/454] drm/vc4: clean up error handling on devm_kzalloc
|
||
|
|
failure
|
||
|
|
|
||
|
|
The current error handling when devm_kzalloc fails performs a
|
||
|
|
non-null check on connector which is redundant because connector
|
||
|
|
is null at that failure point. Once this is removed, make the
|
||
|
|
failure path into a trivial -ENOMEM return to clean up the
|
||
|
|
error handling. Also remove need to initialize connector to NULL.
