To me, missing argument after opening parenthesis, looks worse. I would
prefer:
exynos_dp_write_byte_to_dpcd(dp,
Why you moved the 'dp' argument to new line?
Hmm... Just like style tool indicate, no more warning after
that change.
For now, I would like to follow the original style, just improved
some obvious style problem. :-)
What was the checkpatch warning that said 'dp' has to move to new line?
I tried this and I don't see it.
checkpatch haven't remind me that put dp to new line would fix
this warning, this just come from my experiments. And I works,
no more warnings from checkpatch, so I toke this style.
Checkpatch isn't a great arbiter of style.
It's just a brainless tool.
Always use your instead of anything brainless.
If it were code I was writing, I'd ignore 80 columns warnings
where appropriate.
These are long function names and long macro defines, so it's
inappropriate to use 80 columns as a guiding style.
I'd write:
exynos_dp_read_byte_from_dpcd(dp, DP_TEST_REQUEST,
&test_vector);
if (test_vector & DP_TEST_LINK_EDID_READ) {
exynos_dp_write_byte_to_dpcd(dp, DP_TEST_EDID_CHECKSUM,
edid[EDID_BLOCK_LENGTH +
EDID_CHECKSUM]);
exynos_dp_write_byte_to_dpcd(dp, DP_TEST_RESPONSE,
DP_TEST_EDID_CHECKSUM_WRITE);
}
So... just ignore the 80 columns warnings. Actually I prefer to
keep the original style in this case.
Thanks,
