48c68c4f1b Drivers: video: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

e31f874584 drivers/video/bf537-lq035.c: use devm_ functions
The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

f8bd493456 video: use gpio_request_one
Using gpio_request_one can make the code simpler because it can
set the direction and initial value in one shot.

70f289db31 fbdev: bf537-lq035: add missing blacklight properties type
Seems this new field was missed, probably due to this driver being merged
around the time this new backlight field was being added.  At any rate,
initial the type field to avoid ugly WARN() dumps.

5dc1365cef drivers/video/bf537-lq035.c: Add missing IS_ERR test
lcd_device_register may return ERR_PTR, so a check is added for this value
before the dereference.  All of the other changes reorganize the error
handling code in this function to avoid duplicating all of it in the added
case.

In the original code, in one case, the global variable fb_buffer was set to
NULL in error code that appears after this variable is initialized.  This
is done now in all error handling code that has this property.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
identifier f;
@@
f(...) { ... return ERR_PTR(...); }

@@
identifier r.f, fld;
expression x;
statement S1,S2;
@@
 x = f(...)
 ... when != IS_ERR(x)
(
 if (IS_ERR(x) ||...) S1 else S2
|
*x->fld
)
// </smpl>
