The quirk to get "acpi_backlight=vendor" behavior by default on the Dell Inspiron 5737 was added before we started doing "acpi_backlight=native" by default on Win8 ready machines. 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).
