[PATCH 4/5] fbdev: Include <linux/io.h> via <asm/fb.h>

From: Thomas Zimmermann

Previous message: Thomas Zimmermann: "[PATCH 2/5] ipu-v3: Include <linux/io.h>"
In reply to: Thomas Zimmermann: "[PATCH 2/5] ipu-v3: Include <linux/io.h>"
Next in thread: Thomas Zimmermann: "[PATCH 5/5] fbdev: Move framebuffer I/O helpers into <asm/fb.h>"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Fbdev's main header file, <linux/fb.h>, includes <asm/io.h> to get
declarations for I/O helper functions. From these declaratons, later
defines framebuffer I/O helpers, such as fb_{read,write}[bwlq]() or
fb_memset().

The framebuffer I/O helpers depend on the system architecture and
will therefore be moved into <asm/fb.h>. Prepare this change by first
adding an include statement for <linux/io.h> to <asm-generic/fb.h>.
Include <asm/fb.h> in all source files that use the framebuffer I/O
helpers, so that they still get the necessary I/O functions.
