Subject: [PATCH] ALSA: hda - Do not assign streams in reverse order
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently stream numbers are assigned in reverse order.
Unfortunately commit 7546abfb8e1f9933b5 ("ALSA: hda - Increment
default stream numbers for AMD HDMI controllers") assumed this was not
the case (specifically, it had the "old cards had single device only"
=> "extra unused stream numbers do not matter" assumption), causing
non-working audio regressions for AMD Radeon HDMI users.
Change the stream numbers to be assigned in forward order.

Message-ID: <1396975740-22160-1-git-send-email-tiwai@suse.de>
From: Takashi Iwai <tiwai@suse.de>
This reverts commit 7546abfb8e1f9933b549f05898377e9444ee4cb2.
The commit [7546abfb: ALSA: hda - Increment default stream numbers for
AMD HDMI controllers] introduced a regression where the AMD HDMI
playback streams don't work properly. As the simplest fix, this patch
reverts that commit.
The upstream code has been changed largely and already contains
another fix (by changing the stream assignment order), this revert
should be applied only to 3.14 kernel where the regression was
introduced.

Greg, there is no upstream commit id due to the reason describe in the
above. It's a simple revert, so please take as is.
thanks,
Takashi
