[PATCH RESEND] fbdev: omapfb: remove unused variable

[PATCH RESEND] fbdev: omapfb: remove unused variable

[Arnd Bergmann]

Removing the default display name left a harmless warning:

fbdev/omap2/omapfb/dss/core.c: In function 'omap_dss_probe':
fbdev/omap2/omapfb/dss/core.c:196:30: error: unused variable 'pdata' [-Werror=unused-variable]

This removes the now-unused variable as well.

It is not lost and will be queued for 4.13 fbdev fixes pull request.

[ The guilty commit went through DRM tree and pulling it into fbdev
  tree just to fix the warning was not feasible.. ]

Ok, thanks a lot!

Yes, I was originally hoping the fix could be merged along with the
patch that introduced the bug. I may have messed up the Cc list for that
though.

Should we add dri-devel as an mailing list entry to the fbdev system in
MAINTAINERS? Iirc there's almost no traffic for fbdev itself, and this
would avoid such a fumble in the future.
