[PATCH] ALSA: usb-audio: Fix wrong kfree issue in snd_usb_endpoint_free_all

Posted by Wan Jiabing 3 years, 11 months ago

Fix following coccicheck error:
./sound/usb/endpoint.c:1671:8-10: ERROR: reference preceded by free on line 1671.

Here should be 'cp' rather than 'ip'.

Fixes: c11117b634f4 ("ALSA: usb-audio: Refcount multiple accesses on the single clock")

Oh, that was a silly failure.
Applied now, thanks!
