[PATCH] DRM DRIVERS: Remove unnecessary test for ARM.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since arch/arm/include/asm/pgtable.h contains:

#define io_remap_pfn_range(vma,from,pfn,size,prot) \
                remap_pfn_range(vma, from, pfn, size, prot)

there is no point treating ARM as a special case in distinguishing
between remap_pfn_range() and io_remap_pfn_range().
