From f5030564938be112183ba3df0cdd6dea3f694c2e Mon Sep 17 00:00:00 2001 From: Lucas Tanure Date: Thu, 23 Feb 2023 08:43:23 +0000 Subject: ALSA: cs35l41: Add shared boost feature Shared boost allows two amplifiers to share a single boost circuit by communicating on the MDSYNC bus. The passive amplifier does not control the boost and receives data from the active amplifier. Shared Boost is not supported in HDA Systems. Based on David Rhodes shared boost patches.

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.
