[MPlayer-users] mga_vid driver: compilation error with remap_page_range

[Derek]

Hi,

It appears that there is an error in drivers/mga_vid.c.
The compiler complains that the function remap_page_range() need more 
than 4 arguments.

In the code, the function is given 5 arguments if the kernel is >= 
2.5.3. It seems to apply to my 2.4.20 kernel source too.

 From /usr/src/linux/include/linux/mm.h:
extern int remap_page_range(struct vm_area_struct *vma, unsigned long 
from, unsigned long to, unsigned long size, pgprot_t prot);

Unfortunately, I do not have older kernel source files to see when this 
change happened...

Regards
Derek
