These functions are MIPS specific arch headers included in
'arch/mips/include/asm'. There is no specific include for this files
in driver code since MIPS platforms include directly this directory
through cflags and driver compiles without problem. But it seems they
are not available directly for randconfigs and a specific include is
needed here? We are currently thinking of a way to move this MIPS
specific stuff into ralink platform code to allow this driver to
properly be compile tested for any architecture [0]. If the specific
MIPS code finally is not moved anywhere, I will send a patch to
explicitly include the MIPS needed headers here.
Best regards,
Sergio Paracuellos
