Add missing braces to include error message. The error message is
related to the return value for sysfs_create_group(). However,
sysfs_create_group() is called when pdata->en_ambl_sens is not zero.
Thus, the checking return value should be included in the if statement.

This is my example conversion of a few existing mmap users. The
fb_mmap() case is a good example because it is a bit more complicated

on the page offset of the mmap (but happily there is never any mixing of

The Freescale DIU supports a 32x32 color hardware cursor. Framebuffer
cursors are monochrome, so the driver converts the image data to the
format that the DIU expects and then programs to hardware accordingly.
The support cursor enabling/disabling, we provide two cursor image buffers.
One is always blank (all zeroes), and the other contains the real cursor
image data. To disable the cursor (used typically for cursor blinking),
we just tell the hardware to use the blank cursor data.

Now that a display timing binding is available, convert our almost identical
binding to use the standard binding.
This patch converts the vt8500 and wm8505 framebuffer drivers and
associated dts/dtsi files to use the standard binding as defined in
bindings/video/display-timing.txt.
There are two side-effects of making this conversion:
1) The fb node should now be in the board file, rather than the soc file as
the display-timing node is a child of the fb node.
2) We still require a bits per pixel property to initialize the framebuffer
for the different lcd panels. Rather than including this as part of the
display timing, it is moved into the framebuffer node.
I have also taken the opportunity to alphabetise the includes of each
driver to avoid double-ups.
