anysee_usb_mutex is initialized at every time the anysee device is probed.
If the second anysee device is probed while anysee_usb_mutex is locked by
the first anysee device, the mutex is broken.
This patch fixes by initialize anysee_usb_mutex statically rather
than initialize at probe time.

When inadvertently hot-unplugging a WT-220U USB DVB-T receiver with
2.6.24, I was met with an oops [1]. The problem is relevant to
2.6.25/26-rc also.
dvb_frontend_init() was called either from re-creation of the kdvb-fe0
thread - seems unlikely, or someone called
dvb_frontend_reinitialise(), causing this path in the thread - really
unlikely, as I can't find any call-site for it.
Either way, quite a number of drivers call dvb_usb_generic_rw() [2]
without checking the validity of the relevant member in the
dvb_usb_device struct - which had changed. Having dvb_usb_generic_rw()
sanity-check and fail (rather than loading from 0x120) seems
reasonable defensive programming [3], in light of it being called in
this way.
The problem with this, is that drivers don't check the return code of
the init call [4]. Does it make sense to cook a patch which allows the
failure to be propagated back up, or am I missing something else?
Thanks,
Daniel

There already is an report at kernel bugzilla about this issue:
http://bugzilla.kernel.org/show_bug.cgi?id=9455
When enabling extra checks for the i2c-bus of cx88 based cards by
loading i2c_algo_bit with bit_test=1 this may trigger an oops
when loading cx88_dvb.
This is caused by the extra check code that detects that the
sda-line is stuck high and thus does not register the i2c-bus.
cx88-dvb however does not check if the i2c-bus is valid and just
uses core->i2c_adap to attach dvb frontend modules.
This leads to an oops at the first call to i2c_transfer:

Impact: driver could possibly stomp on resources outside of its scope
{mchehab@redhat.com: I got two versions of the same patch (identical,
except for whitespacing). One authored by Andy Burns and another
authored by Suresh Siddha. Due to that, I'm applying the one that has
less CodingStyle errors. I'm also adding both comments and the SOB's for
both patches, since they are both interesting}
Suresh Siddha commented:
Alexey Fisher reported:
> resource map sanity check conflict: 0xcfeff800 0xcff007ff 0xcfe00000
> 0xcfefffff PCI Bus 0000:01
BAR base is located in the middle of the 4K page and the hardcoded
size argument makes the request span two pages causing the conflict.
Fix the hard coded size argument in ioremap().
Andy Burns commented:
I have already sent this patch on the linux-dvb list, but it didn't get
much attention, so re-sending direct, I hope you all don't mind.
While attempting to run mythtv in a xen domU, I encountered problems
loading the driver for my saa7134 card, with an error from ioremap().
This error was due to the driver allocating an incorrectly sized mmio
area, which was trapped by xen's permission checks, but this would go
un-noticed on a kernel without xen.
My card has a 1K sized mmio area, I've had information that other cards
have 2K areas, perhaps others have different sizes, yet the driver
always attempts to map 4K. I realise that the granularity of mapping is
the page size, which typically would be 4K, but unless the card's base
address happens to fall on a 4K boundary (mine does not) then the
base+4K will end up spanning two pages, and this is when the error
occurs under xen.
My patch uses the pci_resource_len macro to determine the size required
for the user's particular card, instead of the hardcoded 4K value. I've
tested with a couple of printk() inside ioremap() that the start address
and size do get rounded to the closest page boundary.
With this patch I am able to successfully load the saa7134 driver and
run mythtv under xen with my card, subject to correct pollirq settings
in case of shared IRQ, I am still seeing occasional DMA panics, which I
think are related to swiotlb handling by dom0/domU, usually the panic
occurs when changing mux, once tuned to a mux, 12 hour continuous
recordings are possible without errors.

rather than implementing different ways leading to confusion.
This allows multiple gate_enable/disable's in the tuner_read/write
functions, thereby lesser number of I/O operations throughout,
eventually leading to better results. As a side effect demods that
detect the STOP bit for auto closing of the gate can be avoided, thereby
a very minimal gain in disabling the auto detect feature as well.
Improves readability on the device control.

This fixes hangs on 855-class hardware by avoiding double attachment of the
driver due to the stub second head device having the same pci id as the real
device.
Other DRM drivers probably want this treatment as well, but I'm applying it
just to this one for safety. But we should clean up the drm_pciids.h mess
now so that each driver has its own pci id list header in its own directory.
Lets do that in the next release.

ehc->last_reset is used to ensure that resets are not issued too
close to each other. It's initialized to jiffies minus one minute
on EH entry. However, when new links are initialized after PMP is
probed, new links have zero for this timestamp resulting in long wait
depending on the current jiffies.
This patch makes last_set considered iff ATA_EHI_DID_RESET is set, in
which case last_reset is always initialized. As an added precaution,
WARN_ON() is added so that warning is printed if last_reset is
in future.

Now that the radeon driver has suspend/resume functions, it needs to map its
registers at load time or it will likely crash if a suspend operation occurs
before the driver has been initialized.

the mapping into a _DRM_DRIVER one so that the core won't remove it at

When userland detected that this ioctl was supported (by version number check),
it used it in a racy way -- dispatch delayed swap, wait for vblank, continue
rendering. As there was no mechanism for it to wait for the swap to finish,
sometimes it would render before the swap and garbage would be displayed on
the screen.
By removing the ioctl and returning -EINVAL, userland returns to its previous,
correct rendering path of waiting for a vblank then dispatching a swap. The
only path that could have used this ioctl correctly was page flipping, which
relied on only one client running and emitting wait-for-vblank-before-rendering
in the command stream. That path also falls back correctly, at the performance
cost of not being able to queue up rendering before the flip occurs.

active), leading to glReadPixels failure.

Error handling needs to be modified in dma_pin_iovec_pages().
It should return NULL instead of ERR_PTR
(pinned_list is checked for NULL in tcp_recvmsg() to determine
if iovec pages have been successfully pinned down).
In case of error for the first iovec,
local_list->nr_iovecs needs to be initialized.

If the ioatdma driver is loaded but not used it does not allocate descriptors.
Before it frees channel resources it should first be sure

This patch reverts the following three commits which convert libata to
use block layer tagging.
43a49cbdf31e812c0d8f553d433b09b421f5d52c
e013e13bf605b9e6b702adffbe2853cfc60e7806
2fca5ccf97d2c28bcfce44f5b07d85e74e3cd18e
Although using block layer tagging is the right direction, due to the
tight coupling among tag number, data structure allocation and
hardware command slot allocation, libata doesn't work correctly with
the current conversion.
The biggest problem is guaranteeing that tag 0 is always used for
non-NCQ commands. Due to the way blk-tag is implemented and how SCSI
starts and finishes requests, such guarantee can't be made. I'm not
sure whether this would actually break any low level driver but it
doesn't look like a good idea to break such assumption given the
frailty of ATA controllers.
So, for the time being, keep using the old dumb in-libata qc
allocation.

The "Exclude staging drivers" question is there so that we don't build
staging drivers for allyesconfig or allnoconfig settings, but it's very
irritating when you've already said "no" to staging drivers earlier.
There is absolutely no point in declining twice - once you've declined
the staging drivers, you're done.
So make the second question depend on the first question having been
answered in the affirmative.

It seems that some cards are slightly out of spec and occasionally
will not be able to complete a write in the alloted 250 ms [1].
Incease the timeout slightly to allow even these cards to function
properly.

This Kconfig change allows the common 'make allmodconfig' and
'make allyesconfig' build options to skip the staging tree, which is
probably what you want to have happen anyway.
This makes the linux-next developer's life a lot easier so he doesn't
have to worry about changes that break the staging tree, that's for me
to worry about...
