4 Subject: [PATCH 26/28] ACPI: video: Add dev argument for backlight_device_register
6 This patch set adds generic abstract layer support for acpi video driver to
7 have generic user interface to control backlight and output switch control by
8 leveraging the existing backlight sysfs class driver, and by adding a new
9 video output sysfs class driver.
13 Add dev argument for backlight_device_register to link the class device to
14 real device object. The platform specific driver should find a way to get the
15 real device object for their video device.
