Re: [PATCH 2/2] media: tw9910: solve coding style issues

[jacopo mondi <jacopo@jmondi.org>]

Hi Mauro,
   thanks for doing this.

I didn't dare to touch this driver style issues as it was mainline
already, but since you addressed this I now would have more changes to
apply...

If you move the first line, all the following ones should be be moved
too.

I can send a few patches more on top of this two, to address this and
a few other style issues on this driver.

Would this work for you?

Thanks
