Subject: [PATCH 038/116] ASoC: starfive/jh7110-pwmdac: Convert to platform
|
|
remove callback returning void

The .remove() callback for a platform driver returns an int which makes
|
|
many driver authors wrongly assume it's possible to do error handling by
|
|
returning an error code. However the value returned is ignored (apart
|
|
from emitting a warning) and this typically results in resource leaks.
|
|
|
|
To improve here there is a quest to make the remove callback return
|
|
void. In the first step of this quest all drivers are converted to
|
|
.remove_new(), which already returns void. Eventually after all drivers
|
|
are converted, .remove_new() will be renamed to .remove().
|
|
|
|
Trivially convert this driver from always returning zero in the remove
|
|
callback to the void returning variant.
