Subject: [PATCH 5.16 055/126] ALSA: hda: Fix signedness of sscanf() arguments

From: Takashi Iwai <tiwai@...e.de>

commit 0444f82766f0b5b9c8302ad802dafa5dd0e722d0 upstream.

The %x format of sscanf() takes an unsigned int pointer, while we pass
a signed int pointer.  Practically it's OK, but this may result in a
compile warning.  Let's fix it.

Fixes: a235d5b8e550 ("ALSA: hda: Allow model option to specify PCI SSID alias")
