Subject: arch/unicore32/kernel/setup.c: add generic 'screen_info' to avoid compiling failure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f80561e4d1f95c5e0b8fe4782fcd53618d80a959;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

arch/unicore32/kernel/setup.c: add generic 'screen_info' to avoid compiling failure

Add generic 'screen_info' just like another architectures have done
(e.g. tile, sh, score, ia64, hexagon, and cris).

The related error (with allmodconfig under unicore32):

    LD      init/built-in.o
  drivers/built-in.o: In function `vgacon_save_screen':
