* 'drm-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: drm/radeon/kms: rs600: use correct mask for SW interrupt gpu/drm/radeon/radeon_irq.c: move a dereference below a NULL test drm/radeon/radeon_device.c: move a dereference below a NULL test drm/radeon/radeon_fence.c: move a dereference below the NULL test drm/radeon/radeon_connectors.c: add a NULL test before dereference drm/radeon/kms: fix memory leak drm/kms: Fix &&/|| confusion in drm_fb_helper_connector_parse_command_line() drm/edid: Fix CVT width/height decode drm/edid: Skip empty CVT codepoints drm: remove address mask param for drm_pci_alloc() drm/radeon/kms: add missing breaks in i2c and ss lookups drm/radeon/kms: add primary dac adj values table drm/radeon/kms: fallback to default connector table
