Jaroslav Kysela a474d4ad59 ALSA: usb-audio: Fix possible NULL pointer dereference in snd_usb_pcm_has_fixed_rate() 
[ Upstream commit 92a9c0ad86 ]

The subs function argument may be NULL, so do not use it before the NULL check.

Fixes: 291e9da914 ("ALSA: usb-audio: Always initialize fixed_rate in snd_usb_find_implicit_fb_sync_format()")
