ASoC: stm: stm32_sai_sub: Convert to platform remove callback returning void
[ Upstream commit a3bd37e2e2bce4fb1757a940fa985d556662ba80 ] 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 (mostly) ignored 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. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
