Subject: [PATCH] ALSA: usb-audio: Fix invalid use of sizeof in parse_uac_endpoint_attributes()
Git-commit: 11175556eec58b27a1398e80f8b1302314f2242c
Patch-mainline: v4.19-rc1
References: bsc#1121278
sizeof() when applied to a pointer typed expression gives the
size of the pointer, not that of the pointed data.
Fixes: 7edf3b5e6a45 ("ALSA: usb-audio: AudioStreaming Power Domain parsing")
