From these declaratons, it later defines framebuffer I/O helpers, such as fb_{read,write}[bwlq]() or fb_memset(). 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.When fb.h uses a symbol from io.h, then it shall include that 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.
No problem. That was done with an eye on removing the fb_() macros entirely. But the discussion around patch 5 now goes in a different direction anyway.
Best regards Thomas
Driver source files that already include <asm/io.h> convert to <linux/io.h>.This is a nice cleanup - we should keep that. Sam
