* [media] bttv: fix mutex use before init (BZ#24602)Mauro Carvalho Chehab2010-12-17
| | | | | | | | | | | | | | | | | | | | | | | Fix a regression where bttv driver causes oopses when loading, since it were using some non-initialized mutexes. While it would be possible to fix the issue, there are some other lock troubles, like to the presence of lock code at free_btres_lock(). It is possible to fix, but the better is to just use the core-assisted locking schema. This way, V4L2 core will serialize access to all ioctl's/open/close/mmap/read/poll operations, avoiding to have two processes accessing the hardware at the same time. Also, as there's just one lock, instead of 3, there's no risk of dead locks. The net result is a cleaner code, with just one lock.

* [media] v4l: kill the BKLArnd Bergmann2010-11-08
| | | | | | | | | | | | | | | | | | | All of the hard problems for BKL removal appear to be solved in the v4l-dvb/master tree. This removes the BKL from the various open functions that do not need it, or only use it to protect an open count. The zoran driver is nontrivial in this regard, so I introduce a new mutex that locks both the open/release and the ioctl functions. Someone with access to the hardware can probably improve that by using the existing lock in all cases. Finally, all drivers that still use the locked version of the ioctl function now get called under a new mutex instead of the BKL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes convention of passing a static string as a parameter to another static string. The convention is intended to reduce text usage by sharing the common bits of the string, but the implementation is inherently fragile (a change to one format string but not the other will nullify any possible advantage), it isn't necessarily a net win depending on what this compiler does, and it it reduces code readability.

So make sure we only request the pin on the first setup of a SPI device. Otherwise, if you attempts to reconfigure a SPI device on the fly (like change bit sizes), the setup function incorrectly fails.

The AD7879 data available interrupt signals (DAV) completion, however some X,Y values are not valid because the screen inputs were floating during the acquisition. The AD7877 acts differently here, since it only asserts DAV if the touch is still present when the conversion sequence finished. Based on the fact that this can only happen in the last sample of the repeated conversion sequence, we simply skip the last (short glitches are filtered by the AD7879 internal median and average filters). This doesn't cause noticeable side effects, since the minimum conversion interval is 9.44ms. We receive ~100 waypoint samples per second, so we simply delay the result by 9.44ms. We also reject samples where pressure is greater than pressure_max. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

It is only used by the out-of-tree test module. So it's immediate need is questionable. For maintenance ease it might just get in, as it's very small. John. do you need this in the Kernel, or is it only for osd_ktest.ko? Signed-off-by: John A.

| * | | | | [SCSI] libosd: Support for scatter gather write/read commandsBoaz Harrosh2010-10-26

Scatter-gather enables a write/read of multiple none-contiguous areas of an object, in a single call. The extents may overlap and/or be in any order. The Scatter-Gather list is sent to the target in what is called a "cdb continuation segment". This is yet another possible segment in the osd-out-buffer. It is unlike all other segments in that it sits before the actual "data" segment (which until now was always first), and that it is signed by itself and not part of the data buffer. This is because the cdb-continuation-segment is considered a spill-over of the CDB data, and is therefor signed under OSD_SEC_CAPKEY and higher. TODO: A new osd_finalize_request_ex version should be supplied so the @caps received on the network also contains a size parameter and can be spilled over into the "cdb continuation segment". Thanks to John Chandy <john.chandy@uconn.edu> for the original code, and investigations. And the implementation of SG support in the osd-target.

Also properly support when we don't have any attribute to set while getting a full page. And when clearing an attribute by setting it's size to zero.
