Subject: [PATCH] sparc32 vga support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ac50ab3e45436900b5d73edd0c6b0744af560535;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] sparc32 vga support

sparc32 lacks vga.h, so lots of fbdev drivers won't compile.  There are no
sparc32 systems with PCI slots, so it's a bit moot.

The patch gives sparc32 a copy of the sparc64 vga.h.  It fixes sparc32
allmodconfig without mucking up fbdev Kconfig and gives us wider compile
coverage.
