ASoC: ops: Fix stereo change notifications in snd_soc_put_volsw()
stable inclusion from stable-v5.10.102 commit 0df1badfdfcd94f6bce1b26a1f9d9f4f9d4be92e bugzilla: https://gitee.com/openeuler/kernel/issues/I567K6 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=0df1badfdfcd94f6bce1b26a1f9d9f4f9d4be92e -------------------------------- commit 564778d7 upstream. When writing out a stereo control we discard the change notification from the first channel, meaning that events are only generated based on changes to the second channel. Ensure that we report a change if either channel has changed.
