Revision 030b655b062fe5190fc490e0091ea50307d7a86f authored by Risto Suominen on 25 August 2008, 06:04:23 UTC, committed by Takashi Iwai on 02 October 2008, 10:50:37 UTC
Correct headphone detection for 1st generation iMac G3 Slot-loading (Screamer). This patch fixes the regression in the recent snd-powermac which doesn't support some G3/G4 PowerMacs: http://lkml.org/lkml/2008/10/1/220 Signed-off-by: Risto Suominen <Risto.Suominen@gmail.com> Tested-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Cc: stable@kernel.org Signed-off-by: Takashi Iwai <tiwai@suse.de>
