mtd: physmap_of: fix set but unused warning
drivers/mtd/maps/physmap_of.c: In function ‘of_flash_probe’: drivers/mtd/maps/physmap_of.c:165:16: warning: variable ‘p’ set but not used [-Wunused-but-set-variable] This could be a problem if the 'reg' property is not set, since that means 'count' will be uninitialized.
