Subject: ALSA: hda - Always check array bounds in alc_get_line_out_pfx
From: David Henningsson <[email protected]>
commit 71aa5ebe36a4e936eff281b375a4707b6a8320f2 upstream.
Even when CONFIG_SND_DEBUG is not enabled, we don't want to
return an arbitrary memory location when the channel count is
larger than we expected.
