2011-01-07vga_switcheroo: comparing too few characters in strncmp()Dan Carpenter
This is a copy-and-paste bug. We should be comparing 4 characters here instead of 3. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2011-01-07drm: Update fbdev fb_fix_screeninfoJames Simmons
If you change the color depth via fbset or some other framebuffer aware userland application struct fb_fix_screeninfo is not updated to this new information. This patch fixes this issue. Also the function is changed to just pass in struct drm_framebuffer so in the future we could use more fields. I'm hoping some day fix->smem* could be set here :-) Signed-off-by: James Simmons <jsimmons@infradead.org> Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-01-06drm/radeon: use system_wq instead of dev_priv->wqTejun Heo
With cmwq, there's no reason for radeon to use a dedicated workqueue. Drop dev_priv->wq and use system_wq instead. Because radeon_driver_irq_uninstall_kms() may be called from unsleepable context, the work items can't be flushed from there. Instead, init and flush from radeon_irq_kms_init/fini(). While at it, simplify canceling/flushing of rdev->pm.dynpm_idle_work. Always initialize and sync cancel instead of being unnecessarily smart about it.

2011-01-06drm/radeon/kms: manage r300 CMASK RAM access and allow CMASK clearMarek Olšák
The CMASK RAM is for colorbuffer compression (used in conjunction with MSAA). Only one user (filp) can access it. The CMASK RAM access is managed in the same way as Hyper-Z, but there is a separate ioctl, because an app that uses MSAA does not necessarily have to use zbuffering.

2011-01-06drm/radeon/kms: adjust quirk for acer laptopAlex Deucher
Acer laptop (TravelMate 5730G) has an HDMI connector on the laptop and a DVI connector on the docking station and both share the same encoder, hpd pin, and ddc line. The bios connector table reflects this and is technically correct, however, we drop the DVI connector here since xrandr has no concept of encoders (only crtcs and connectors) and will try and drive both connectors with different crtcs which isn't possible on the hardware side and leaves no crtcs for LVDS or VGA.

2010-12-30Revert "Staging: zram: work around oops due to startup ordering snafu"Nitin Gupta
This reverts commit 7e24cce38a99f373450db67bf576fe73e8168d66 because it was never appropriate for mainline. Do not check for init flag before starting I/O - zram module is unusable without this fix. The oops mentioned in the reverted commit message was actually a problem only with the zram version as present in project's own repository where we allocate struct zram_stats_cpu upon device initialization. OTOH, In mainline/staging version of zram, we allocate struct stats upfront, so this oops cannot happen in mainline version. Checking for init_done flag in zram_make_request() results in a *no-op* for any I/O operation since we simply always return success. This flag is actually set when the first write occurs on a zram disk which triggers its initialization.

2010-12-29spi/omap2_mcspi.c: Force CS to be in inactive state after off-mode transitionGregory CLEMENT
When SPI wake up from OFF mode, CS is in the wrong state: force it to the inactive state. During the system life, I monitored the CS behavior using a oscilloscope. I also activated debug in omap2_mcspi, so I saw when driver disable the clocks and restore context when device is not used.Each time the CS was in the correct state. It was only when system was put suspend to ram with off-mode activated that on resume the CS was in wrong state( ie activated). Changelog: * Change from v1 to v2: - Rebase on linus/master (after 2.6.37-rc1) - Do some clean-up and fix indentation on both patches - Add more explanations for patch 2 * Change from v2 to v3: - Use directly resume function of spi_master instead of using function - from spi_device as Grant Likely pointed it out. - Force this transition explicitly for each CS used by a device. * Change from v3 to v4: - Patch clean-up according to Kevin Hilman and checkpatch. - Now force CS to be in inactive state only if it was inactive when it was suspended. * Change from v4 to v5: - Rebase on linus/master (after 2.6.37-rc3) - Collapse some lines as pointed by Grant Likely - Fix a spelling * Change from v5 to v6: - Rebase on linus/master (after 2.6.37-rc7) - Use CONFIG_SUSPEND instead of CONFIG_PM - Didn't use legacy PM methods anymore. Instead, add a struct dev_pm_ops and add the resume method there. - Fix multi-line comment style * Change from v6 to v7: - Rebase on linus/master (after 2.6.37-rc8) - Drop an extra line Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Reviewed-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2010-12-24libata: issue DIPM enable commands with LPM state updatedTejun Heo
Low level drivers may behave differently depending on the current link->lpm_policy. During ata_eh_set_lpm(), DIPM enable commands are issued after the successful completion of ap->ops->set_lpm(), which means that the controller is already in the target state. This causes DIPM enable commands to be processed with mismatching controller power state and link->lpm_policy value. In ahci, link->lpm_policy is used to ignore certain PHY events if LPM is enabled; however, as DIPM commands are issued with stale link->lpm_policy, they sometimes end up triggering these conditions and get aborted leading to LPM configuration failure. Fix it by updating link->lpm_policy before issuing DIPM enable commands.
