[PATCH] drm/gma500: Remove unused mrst_helper_funcs

[PATCH] drm/gma500: Remove unused mrst_helper_funcs

[linux]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

The mrst_helper_funcs const was added in 2013 by
commit ac6113ebb70d ("drm/gma500/mrst: Add SDVO clock calculation")
and commented as 'Not used yet'.

It's not been used since, so remove it.

You talk about mrst_helper_funcs but the patch removes
mrst_clock_funcs. I assume this is not intentional.

Hi Patrik,

Oops! Thanks for spotting that, I'll send a v2 fixing the commit
message; I think I was intending to write something like
'the helper functions it references are still used elsewhere.'

v2 coming up soon.
