Subject: ARM: mmu: Call debug_ll_io_init if no map_io function is specified
X-Git-Url: https://rtime.felk.cvut.cz/gitweb/linux-imx.git/commitdiff_plain/bc37324e820e4a23a0bccef79ae797ce4d939c4f

ARM: mmu: Call debug_ll_io_init if no map_io function is specified

More and more sub-architectures are using only the debug_ll_io_init
function as the map_io function. Make the core code call this function
if no function is specified in the machine description to remove some
boilerplate code.
