but it is introducing two new build warnings:
drivers/staging/sm750fb/sm750_hw.c: In function ‘hw_sm750_map’:
drivers/staging/sm750fb/sm750_hw.c:67:2: warning: passing argument 1 of ‘ddk750_set_mmio’ discards ‘volatile’ qualifier from pointer target type [enabled by default]
In file included from drivers/staging/sm750fb/ddk750_mode.h:4:0,
from drivers/staging/sm750fb/ddk750.h:15,
from drivers/staging/sm750fb/sm750_hw.c:24:
and
drivers/staging/sm750fb/ddk750_chip.h:77:6: note: expected ‘void *’ but argument is of type ‘volatile unsigned char *’
care to make another patch to solve these two new warnings, and send this patch and the new one in a series and while sending mark the version number in the subject.
