In nes_create_qp(), the test

	if (nesqp->mmap_sq_db_index > NES_MAX_USER_WQ_REGIONS) {

is used to error out if the db_index is too large; however, if the
test doesn't trigger, then the index is used as

	nes_ucontext->mmap_nesqp[nesqp->mmap_sq_db_index] = nesqp;

and mmap_nesqp is declared as

	struct nes_qp      *mmap_nesqp[NES_MAX_USER_WQ_REGIONS];

which leads to an array overrun if the index is exactly equal to
NES_MAX_USER_WQ_REGIONS.  Fix this by bailing out if the index is
greater than or equal to NES_MAX_USER_WQ_REGIONS.

This was spotted by the Coverity checker (CID 2162).

In file included from drivers/media/video/zoran_procfs.c:50:

The reason is that drivers/media/video/zoran.h defines an enum with

Signed-off-by: NMauro Carvalho Chehab <mchehab@infradead.org>

This patch combines all the finished discussions and its resulting patches from
the mailing list.

The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of
small issues, that are fixed with this patch now. For me the most interesting
thing is, that it's now safer to use it on other architectures.

The history for version 1.0.6 is:
- fixed coverity checker warnings in *_usb_driver_disconnect
- probe()/open() race by correct ordering in probe()
- DMA coherency rules by separate allocation of all buffers
- use of endianness macros
- abuse of spinlock, replaced by mutex
- racy handling of timer in disconnect, replaced by delayed_work
- racy interruptible_sleep_on(), replaced with wait_event_interruptible()
- handle signals in read()

The driver is tested with all Debian/testing radio programs and rdsd. The patch
is tested against checkpatch.pl v1.12.

em28xx driver is capable of handling more than one usb device. However, isoc
transfers require a large amount of data to be transfered.

Before this patch, just one em28xx board were enough to allocate more than 50%
URBs:

T:  Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=480 MxCh= 8
B:  Alloc=480/800 us (60%), #Int=  0, #Iso=  2
D:  Ver= 2.00 Cls=09(hub  ) Sub=00 Prot=01 MxPS=64 #Cfgs=  1

So, only one board could use an USB host at the same time. After the patch, it
is possible to use more than one em28xx at the same time, on the same usb host,
if the image size is slower or equal to 345600, since those images will
require about 30% of the URBs:

T:  Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=480 MxCh= 8
B:  Alloc=232/800 us (29%), #Int=  0, #Iso=  2
D:  Ver= 2.00 Cls=09(hub  ) Sub=00 Prot=01 MxPS=64 #Cfgs=  1

So, in thesis, after the patch, it would be possible to use up to 3 boards by
each usb host, if the devices are generating small images.
