From: Greg KH <gregkh@linuxfoundation.org>
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit 6e1c39c6b00d9141a82c231ba7c5e5b1716974b2 upstream.
The recent fix for power-map controls (commit b0791dda813) caused regressions on some other HP laptops. They have fixed pins but these pins are exposed as jack-detectable. Thus the driver tries to control the power-map dynamically per jack detection where it never gets on.
This patch corrects the condition check for fixed pins so that the power-map is set always for these pins.
NOTE: this is no simple backport from 3.5 kernel. Since 3.5 kernel had significant code change in the relevant part, I fixed this differently.
