[PATCH 0947/1285] Replace numeric parameter like 0444 with macro

[PATCH 0947/1285] Replace numeric parameter like 0444 with macro

[Baole Ni]

I find that the developers often just specified the numeric value
when calling a macro which is defined with a parameter for access permission.
As we know, these numeric value for access permission have had the corresponding macro,
and that using macro can improve the robustness and readability of the code,
thus, I suggest replacing the numeric parameter with the macro.

Gah!

A patch series with 1285 patches with identical subject!

Please don't ever do something like that. My inbox is not trash!

Instead, please group the changes per subsystem, and use different
names for each patch. Makes easier for people to review.

also, you need to send the patches to the subsystem mainatiner, and
not adding a random list of people like this:

To: gregkh@linuxfoundation.org, maurochehab@gmail.com, mchehab@infradead.org, mchehab@redhat.com, m.chehab@samsung.com, m.szyprowski@samsung.com, kyungmin.park@samsung.com, k.kozlowski@samsung.com

Btw, use *just* the more recent email of the maintainer, instead of
spamming trash to all our emails (even to the ones that we don't use
anymore!

I'll just send all those things to /dev/null until you fix your
email sending process.

Regards,
Mauro

There are people at Intel who know about things like this.

Hi Baole,

It may also be worth waiting for the first group to be reviewed before
sending the other groups, in case the review comments change what you
send later.

There's an S_IRUGO macro which makes the above just 'S_IRUGO | S_IWUSR'.
