The variable has become unused in modular configurations
which triggers a harmless warning:

drivers/video/fbdev/matrox/matroxfb_base.c:1583:12: error: 'hotplug' defined but not used [-Werror=unused-variable]

This moves it into an #ifdef section of the file, matching
all its references.

Instead check info->ops->owner, which amounts to the same.

Spotted because I want to remove the pile of broken and cargo-culted
fb_info->flags assignments in drm drivers.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  19884	   3036	     96	  23016	   59e8	fbdev/matrox/matroxfb_base.o

File size after adding 'const':
   text	   data	    bss	    dec	    hex	filename
  20300	   2620	     96	  23016	   59e8	fbdev/matrox/matroxfb_base.o

My static checker is complaining because we check "drv" for NULL and
then we dereference it to get the next item in the list.  It can't be
NULL so we can remove this check.

Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. These were identified during
allyesconfig builds of x86, arm, and arm64, with most initializer fixes
extracted from grsecurity.

hw->DACreg has a size of 80 bytes and MGADACbpp32 has 21. So when
memcpy copies MGADACbpp32 to hw->DACreg it copies 80 bytes but
only 21 bytes are valid.

For structure types defined in the same file or local header files, find
top-level static structure declarations that have the following
properties:
1. Never reassigned.
2. Address never taken
3. Not passed to a top-level macro call
4. No pointer or array-typed field passed to a function or stored in a
variable.
Declare structures having all of these properties as const.

Done using Coccinelle.

Drivers should include asm/pci-bridge.h only when they need the arch-
specific things provided there.  Outside of the arch/ directories, the only
drivers that actually need things provided by asm/pci-bridge.h are the
powerpc RPA hotplug drivers in drivers/pci/hotplug/rpa*.

Remove the includes of asm/pci-bridge.h from the other drivers, adding an
include of linux/pci.h if necessary.
