Hi Ricardo,

I currently have a patch series awaiting the final ok which includes
fixes for these warnings
(http://lkml.iu.edu/hypermail/linux/kernel/1503.1/02535.html),
apologies but assuming there isn't something hideously wrong with my
series I suspect they supersedes this patch :(

It's really easy to accidentally submit a patch that has already been
covered elsewhere; I, as a rather new kernel contributor, always find
I have to search quite a bit to be *sure* that it's not been covered
already.

Additionally, your subject line is 'staging/sm75fb: Declare static
functions as such' which ought to be 'staging: sm750fb: Declare static
functions as such' - there's a typo in the device name and I think the
convention is always to use colons in subject lines.

Best,

Sorry about that, I did pull from linux-next and I am crealy not
subscribed to the right mailing list.

I miss something like the properly maintained patchwork on
linux-media. It works really well to see what is on the pipeline. I
honestly never thought that somebody will take a look to this driver
:)

About the typo, you are right of course :)

Regarding the colon, there is no convention about that, every
subsystem has its own preference. I prefer / than :

I agree that is your patch that should be pulled, not this one. But I
think you should split your patch in one patch per file.

All that said

Best,
