This patch replaces all occurences of the macro DEV_OK by the actual value 0 at the driver level. So this patch touch the files under drivers/, include/ and samples/drivers/. This patch is part of the effort to transition from DEV_* codes to errno.h codes. Change-Id: I69980ecb9755f2fb026de5668ae9c21a4ae62d1e Signed-off-by: Andre Guedes <andre.guedes@intel.com>
