4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Zimmermann <tzimmermann@suse.de>
commit 7b91d017f77c1bda56f27c2f4bbb70de7c6eca08 upstream.
Struct gpio_backlight_platform_data refers to a platform device within
the Linux device hierarchy. The test in gpio_backlight_check_fb()
compares it against the fbdev device in struct fb_info.dev, which
is different. Fix the test by comparing to struct fb_info.device.
Fixes a bug in the backlight driver and prepares fbdev for making
struct fb_info.dev optional.
v2:
* move renames into separate patch (Javier, Sam, Michael)

4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Zimmermann <tzimmermann@suse.de>
commit 4cfe75f0f14f044dae66ad0e6eea812d038465d9 upstream.
Fix the test for the AST2200 in the DRAM initialization. The value
in ast->chip has to be compared against an enum constant instead of
a numerical value.
This bug got introduced when the driver was first imported into the
kernel.
