Greg Kroah-Hartman 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.

Peter Senna Tschudin 4aedf566f2 drivers/video/mb862xx/mb862xxfbdrv.c: fix error return code
Convert a nonnegative error return code to a negative one, as returned
elsewhere in the function.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>

H Hartley Sweeten b71b763339 video: mb862xxfbdrv.c: local functions should not be exposed globally
Functions not referenced outside of a source file should be marked
static to prevent them from being exposed globally.

Quiets the sparse warnings:

warning: symbol 'mb862xx_intr' was not declared. Should it be static?

Paul Gortmaker 355b200bac video: Add module.h to drivers/video files who really use it.
They were getting this implicitly by an include of module.h
from device.h -- but we are going to clean that up and break
that include chain, so include module.h explicitly now.

Yong Zhang f8798ccbef video: irq: Remove IRQF_DISABLED
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.

Laurent Pinchart 23dc8b1c07 mb862xxfb: use display information in info not in var for panning
We must not use any information in the passed var besides xoffset,
yoffset and vmode as otherwise applications might abuse it.

Joe Perches 28f65c11f2 treewide: Convert uses of struct resource to resource_size(ptr)
Several fixes as well where the +1 was missing.

Done via coccinelle scripts like:

@@
struct resource *ptr;
@@

- ptr->end - ptr->start + 1
+ resource_size(ptr)

and some grep and typing.

Mostly uncompiled, no cross-compilers.
