Subject[PATCH] x86/simplefb: simplefb was broken on Oracle and HP system, skip VIDEO_TYPE_EFI
Date
As descriped in https://bugzilla.kernel.org/show_bug.cgi?id=98721
When kernel 4.0.4 was tested on Oracle and HP system with UEFI mode, no output and
login on console.

Simplefb was broken on these systems when orig_video_isVGA is VIDEO_TYPE_EFI, so
skip it.

This patch was tested on Oracle Sun server X5-2 series and HP ProLiant DL380 Gen9
with kernel 4.0.4
