Nikita Kiryushin 39af144b6d ACPI: video: check for error while searching for backlight device parent ... [ Upstream commit ccd45faf49 ] If acpi_get_parent() called in acpi_video_dev_register_backlight() fails, for example, because acpi_ut_acquire_mutex() fails inside acpi_get_parent), this can lead to incorrect (uninitialized) acpi_parent handle being passed to acpi_get_pci_dev() for detecting the parent pci device. Check acpi_get_parent() result and set parent device only in case of success. Found by Linux Verification Center (linuxtesting.org) with SVACE. Fixes: 9661e92c10 ("acpi: tie ACPI backlight devices to PCI devices if possible") Signed-off-by: Nikita Kiryushin <kiryushin@ancud.ru> Signed-off-by: Rafael J.
