[PATCH] staging: sm750fb: Refine the code and remove unused code.

[Dan Carpenter]

So, when I'm reviewing these, there are obviously a lot of patches that
go through staging and I try to do them as fast as possible and quite
often make mistakes.  Feel free to speak up when that happens, I won't
be offended.

I use a script to review them which strips our all the white space
changes because I don't care about those really.  I mostly care about
bugs.

The problem is that this patch removes some extra curly braces:

                if (!(PEEK32(PANEL_PLL_CTRL) & PLL_CTRL_POWER) ||
-                   !(PEEK32(PANEL_DISPLAY_CTRL) & DISPLAY_CTRL_TIMING)) {
+		    !(PEEK32(PANEL_DISPLAY_CTRL) & DISPLAY_CTRL_TIMING))
                        return;
-                }

If the patch had *just* deleted the tabs, this would have been basically
a 20 second review.

Anyway, I've reviewed it now and it's fine.  But next time, please don't
mix those kinds of white space changes.  It seems tiny but it messes
with my scripts.
