video: clps711x: Add new Cirrus Logic CLPS711X framebuffer driver

This adds support for the framebuffer available in the Cirrus
Logic CLPS711X CPUs.
FB features:
- 1-2-4 bits per pixel.
- Programmable panel size to a maximum of 1024x256 at 4 bps.
- Relocatible Frame Buffer (SRAM or SDRAM).
- Programmable refresh rates.
- 16 gray scale values.
This new driver is designed to usage with devicetree only.
The driver have been tested with custom board equipped
Cirrus Logic EP7312.

video: msm: Introduce the use of the managed version of kzalloc

This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
functions. Also, linux/device.h is added to make sure the devm_*()
routine declarations are unambiguously available. The function
mddi_dummy_remove is removed as it is no longer required after
removing the kfree. The variable ret is also done away with.

The following Coccinelle semantic patch was used for making a part of
the change:

@platform@
identifier p, probefn, removefn;
@@
struct platform_driver p = {
  .probe = probefn,
  .remove = removefn,
};

@prb@
identifier platform.probefn, pdev;
expression e, e1, e2;
@@
probefn(struct platform_device *pdev, ...) {
  <+...
- e = kzalloc(e1, e2)
+ e = devm_kzalloc(&pdev->dev, e1, e2)
  ...

  ...+>
}

@rem depends on prb@
identifier platform.removefn;
expression e;

video: 68328fb: remove check for CONFIG_FB_68328_INVERT

Since v2.6.7 the 68328 frame buffer driver contains a check for
CONFIG_FB_68328_INVERT. But the Kconfig symbol FB_68328_INVERT was never
added to the tree. Remove this check and do some related cleaning up.

drivers/video/fbdev : dereference without an error test

After a variable is assigned the result of backlight_device_register, an
error test should be performed before a dereference.

as follows:

x@p0 = backlight_device_register(...)

The surrounding code and the fact that the previous two if's are

are greater than SIS_661==15) suggests that the "else" is indeed
missing.

mtd: lpc32xx: drop bitflip_threshold initialization

These drivers don't need to explicitly initialize their bitflip
thresholds. The comment is no longer correct, since nand_scan_tail()
performs this initialization as of the following commit:

    commit ea3b2ea24ef0f2ef9c6795b19cff456195b6728a
    Author: Shmulik Ladkani <shmulik@jungo.com>
    Date:   Fri Jun 8 18:29:06 2012 +0300

(It seems there were some parallel efforts on writing/submitting these
drivers, and Shmulik's bug fix.)
