gpu: drm: radeon: Fix a possible null-pointer dereference in radeon_connector_set_property()

2019-10-07T16:58:38Z

[ Upstream commit f3eb9b8f67bc28783eddc142ad805ebdc53d6339 ] In radeon_connector_set_property(), there is an if statement on line 743 to check whether connector->encoder is NULL: if (connector->encoder) When connector->encoder is NULL, it is used on line 755: if (connector->encoder->crtc) Thus, a possible null-pointer dereference may occur. To fix this bug, connector->encoder is checked before being used. This bug is found by a static analysis tool STCheck written by us.

[ Upstream commit 6f7fe9a93e6c09bf988c5059403f5f88e17e21e6 ] During kexec some adapters hit an EEH since they are not properly shut down in the radeon_pci_shutdown() function. Adding radeon_suspend_kms() fixes this issue. Signed-off-by: KyleMahlkuch Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

mm/mmu_notifier: convert user range->blockable to helper function

2019-05-14T16:47:49Z

Use the mmu_notifier_range_blockable() helper function instead of directly dereferencing the range->blockable field. This is done to make it easier to change the mmu_notifier range field. This patch is the outcome of the following coccinelle patch: %<------------------------------------------------------------------- @@ identifier I1, FN; @@ FN(..., struct mmu_notifier_range *I1, ...) { <... -I1->blockable +mmu_notifier_range_blockable(I1) ...> } ------------------------------------------------------------------->% spatch --in-place --sp-file blockable.spatch --dir .
