The framebuffer I/O helpers pre-date Linux' current I/O code and will
be replaced by regular I/O helpers. Prepare this change by adding an
include statement for <linux/io.h> to all source files that use the
framebuffer I/O helpers. They will still get declarations of the I/O
functions even after <linux/fb.h> has been cleaned up.
file so it is self contained.
So it is wrong to push the io.h include to the users of
fb_{read,write,xxx}. Maybe fb.h only uses macros as is the case here,
but that is no excuse nt to include io.h.
Drop these changes.
Driver sourceThis is a nice cleanup - we should keep that.
files that already include <asm/io.h> convert to <linux/io.h>.
