ALSA: hda: Add error check for snd_ctl_rename_id() in snd_hda_create_dig_out_ctls()
commit 822b7ec657e99b44b874e052d8540d8b54fe8569 upstream. Check the return value of snd_ctl_rename_id() in snd_hda_create_dig_out_ctls(). Ensure that failures are properly handled. [ Note: the error cannot happen practically because the only error condition in snd_ctl_rename_id() is the missing ID, but this is a rename, hence it must be present. But for the code consistency, it's safer to have always the proper return check -- tiwai ] Fixes: 5c219a34 ("ALSA: hda: Fix kctl->id initialization") Cc: stable@vger.kernel.org # 6.4+ Signed-off-by:Wentao Liang <vulab@iscas.ac.cn> Link: https://patch.msgid.link/20250213074543.1620-1-vulab@iscas.ac.cn Signed-off-by:
