Subject: [PATCH] ALSA: usb-audio: Fix a limit check in proc_dump_substream_formats()
Git-commit: 8137d2763bf77d68babb38a7323c5152c945f20e
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518
This should be ARRAY_SIZE() instead of sizeof(). The sizeof() limit is
too high so it doesn't work.
Fixes: 093b8494f299 ("ALSA: usb-audio: Print more information in stream proc files")
