Since commit 20cde694027e ("x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()") in the 3.17 merge window, the EFI framebuffer depends on the VGA arbitration layer. However, the configuration does not reflect this, which leads to a hard-to-find bug when FB_EFI is configured without VGA_ARB. Add a select clause to remedy this.
Cc: Bruno Prémont <bonbons@linux-vserver.org> Signed-off-by: Henrik Rydberg <rydberg@euromail.se> --- Hi Peter,
I stumbled upon this bug from the 3.17 merge window when updating to Linus's 3.18 git head yesterday. The patch has been tested on two different EFI machines; one that needs the patch and one that does not.
Thanks, Henrik
