drivers/platform/olpc/olpc-ec.c: initialise earlier

2013-08-29T16:47:38Z

commit 93dbc1b3b506e16c1f6d5b5dcfe756a85cb1dc58 upstream. Being a low-level component, various drivers (e.g. olpc-battery) assume that it is ok to communicate with the OLPC Embedded Controller during probe. Therefore the OLPC EC driver must be initialised before other drivers try to use it. This was the case until it was recently moved out of arch/x86 and restructured around commits ac2504151f5a ("Platform: OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86: OLPC: switch over to using new EC driver on x86"). Use arch_initcall so that olpc-ec is readied earlier, matching the previous behaviour. Fixes a regression introduced in Linux-3.6 where various drivers such as olpc-battery and olpc-xo1-sci failed to load due to an inability to communicate with the EC. The user-visible effect was a lack of battery monitoring, missing ebook/lid switch input devices, etc. Signed-off-by: Daniel Drake Cc: Andres Salomon Cc: Paul Fox Cc: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds Signed-off-by: Greg Kroah-Hartman

hp_accel: Ignore the error from lis3lv02d_poweron() at resume

2013-05-08T23:59:44Z

The error in lis3lv02_poweron() is harmless in the resume path, so we should ignore it. It is inline with the other usages of lis3lv02_poweron() and matches the 3.0 code for this routine. This patch is in suse git and might have missed making it into the mainline. opensuse - commit id: 66ccdac87c322cf7af12bddba8c805af640b1cff Signed-off-by: Takashi Iwai Signed-off-by: Shuah Khan CC: stable@vger.kernel.org 3.8, 3.4, 3.5, 3.2 Signed-off-by: Matthew Garrett
