Subject: [PATCH] ALSA: hda: cs35l41: mark cs35l41_verify_id() static

From: Arnd Bergmann <arnd@...db.de>

The newly introduced function is global but only called in this one
file and has no extern prototype, so it should probably be static:

sound/pci/hda/cs35l41_hda.c:733:5: error: no previous prototype for 'cs35l41_verify_id' [-Werror=missing-prototypes]
  733 | int cs35l41_verify_id(struct cs35l41_hda *cs35l41, unsigned int *regid, unsigned int *reg_revid)

Fixes: 881b7bce0c25 ("ALSA: hda: cs35l41: Run boot process during resume callbacks")
