Subject: backlight/gpio_backlight: Rename field 'fbdev' to 'dev'
X-Git-Tag: v6.6.17~3937^2~23^2~113
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ed369def91c1579a34cd6f9494e4614745430322;p=platform%2Fkernel%2Flinux-rpi.git

backlight/gpio_backlight: Rename field 'fbdev' to 'dev'

Rename the field 'fbdev' in struct gpio_backlight_platform_data and
struct gpio_backlight to 'dev', as they store pointers to the Linux
platform device; not the fbdev device. Makes the code easier to
understand.
