Since we now avoid using acpi-video as backlight driver on these machines by default (using the native driver instead) we no longer need this quirk. Moreover the vendor driver does not work after a suspend/resume where as the native driver does. This reverts commit 08a56226d847 ("ACPI / video: Add Dell Inspiron 5737 to the blacklist"). BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=111061 Cc: stable@xxxxxxxxxxxxxxxOK, but I think we need to limit the range of "stable" kernels this is going to go into. What's the least recent "stable" series one you'd like this to be applied to?
3.19 and later have this commit: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/acpi/video.c?id=fbc9fe1b4f222a7c575e3bd8e9defe59c6190a04 And thus will use native backlight by default, so anything >= 3.19. Regards, Hans
