    Subject[PATCH 01/11] x86: sysfb: fool-proof CONFIG_X86_SYSFB
    Date
    Turns out, people do not read help-texts of new config-options and enable
    them nonetheless. So several reports came in with X86_SYSFB=y and
    FB_SIMPLE=n, which in almost all situations prevents firmware-fbs from
    being probed.

    X86_SYSFB clearly states that it turns legacy vesa/efi framebuffers into a
    format compatible to simplefb (and does nothing else..). So to avoid
    further complaints about missing gfx-support during boot, simply depend on
    FB_SIMPLE now.
    As FB_SIMPLE is disabled by default and usually only enabled on selected
    ARM architectures, x86 users should thus never see the X86_SYSFB
    config-option. And if they do, everything is fine as simplefb will be
    available.

    Note that most of the sysfb code is enabled independently of X86_SYSFB.
    The config option only selects a compatibility mode for simplefb. It was
    introduced to ease the transition to SimpleDRM and disabling fbdev. As
    this is still ongoing, there's no need for non-developers to care for
    X86_SYSFB so we can safely hide it behind FB_SIMPLE.
