i915_driver_load adds a write-combining MTRR region for the GTT aperture to improve memory speeds through the aperture. If i915_driver_load fails after this, it would not have cleaned up the MTRR. This shouldn't cause any problems, except for consuming an MTRR register. Still, it's best to clean up completely in the failure path, which is easily done by calling mtrr_del if the mtrr was successfully allocated. i915_driver_load calls i915_gem_load which register i915_gem_inactive_shrink. If i915_driver_load fails after calling i915_gem_load, the shrinker will be left registered. When called, it will access freed memory and crash. The fix is to unregister the shrinker in the failure path using code duplicated from i915_driver_unload. i915_driver_load also has some incorrect gotos in the error cleanup paths: * After failing to initialize the GTT (which cannot happen, btw, intel_gtt_get returns a fixed (non-NULL) value), it tries to free the uninitialized WC IO mapping. Fixed this by changing the target from out_iomapfree to out_rmmap Signed-off-by: NKeith Packard <keithp@keithp.com> Tested-by: NLin Ming <ming.m.lin@intel.com>

Patch 2e711c04 (PM: Remove sysdev suspend, resume and shutdown operations) deleted sysdev_suspend(), which was being relied on to call check_wakeup_irqs() in suspend. If check_wakeup_irqs() is not called, wake interrupts that are pending when suspend is entered may be lost. It also breaks IRQCHIP_MASK_ON_SUSPEND, which is handled in check_wakeup_irqs(). This patch adds a call to check_wakeup_irqs() in syscore_suspend(), similar to what was deleted in sysdev_suspend(). Signed-off-by: NColin Cross <ccross@android.com> Signed-off-by: NRafael J.

This driver handles the variants pca9530-pca9533, so it chose the name "pca953x". However, there is a gpio driver which decided on the same name. As a result, those two can't be loaded at the same time. Add a subsystem prefix to make the driver name unique.

Commit e534c5b8 (USB: fix regression occurring during device removal) didn't go far enough. It failed to take into account that when a driver claims multiple interfaces, it may release them all at the same time. As a result, some interfaces can get released before they are unregistered, and we deadlock trying to acquire the bandwidth_mutex that we already own.
