drm/nouveau: Fix reference count leak in nouveau_connector_detect

2020-09-03T09:19:24+00:00

[ Upstream commit 990a1162986e8eff7ca18cc5a0e03b4304392ae2 ] nouveau_connector_detect() calls pm_runtime_get_sync and in turn increments the reference count. In case of failure, decrement the ref count before returning the error. Signed-off-by: Aditya Pakki Signed-off-by: Ben Skeggs Signed-off-by: Sasha Levin

drm/imx: imx-ldb: Disable both channels for split mode in enc->disable()

drm/vmwgfx: Fix two list_for_each loop exit tests

2020-08-21T08:53:07+00:00

[ Upstream commit 4437c1152ce0e57ab8f401aa696ea6291cc07ab1 ] These if statements are supposed to be true if we ended the list_for_each_entry() loops without hitting a break statement but they don't work. In the first loop, we increment "i" after the "if (i == unit)" condition so we don't necessarily know that "i" is not equal to unit at the end of the loop. In the second loop we exit when mode is not pointing to a valid drm_display_mode struct so it doesn't make sense to check "mode->type".
