2014-01-06mfd: Constify struct mfd_cell where possibleGeert Uytterhoeven
As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting refcounting pointers in original mfd_cell arrays"), the "cell" parameter of mfd_add_devices() is "const" again. Hence make all cell data passed to mfd_add_devices() const where possible. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
