ALSA: usb-audio: Add error checks for usb_driver_claim_interface() calls
[ Upstream commit 5fb45414ae03421255593fd5556aa2d1d82303aa ]
There are a few calls of usb_driver_claim_interface() but all of those
miss the proper error checks, as reported by Coverity. This patch
adds those missing checks.
Along with it, replace the magic pointer with -1 with a constant
USB_AUDIO_IFACE_UNUSED for better readability.
