Thanks for your reply, but I do think that fix code style and make 
checkpatch.pl passed is my primary reason to submit this patch. I can't 
think out more directly words ;( ,

Okay, I think it would be better to modify like those:

retval = exynos_dp_read_bytes_from_i2c(
                dp, I2C_EDID_DEVICE_ADDR,
                EDID_HEADER_PATTERN,
                EDID_BLOCK_LENGTH,
                &edid[EDID_HEADER_PATTERN]);


Is it okay ?
