ep93xx-fb.c uses interfaces from linux/module.h,
so it should include that file.  This patch fixes below build errors.

What actually changed to make these files broken? Did some other header
previously include module.h for us? How many other drivers are broken?

Anyway, the change is okay.

Actually, having a second look at this it does not look right.

drivers/video/ep93xx-fb.c includes linux/platform.h (as its first include),
which includes linux/driver.h, which includes linux/module.h.

Just tested on Linus' latest tree and both this driver and the ep93xx
backlight driver build fine. What kernel version are you using?

hi Ryan,

The patch is against linux-next tree.
I got build error for ep93xx-fb.c and ep93xx_bl.c on linux-next tree.
( next-20110819 )
