2017-02-08[media] ttpci: address stringop overflow warningArnd Bergmann2-10/+10

Changing the sizes to 'unsigned int' instead seems safe as we already check for maximum sizes, and it also simplifies the code a bit.

2017-01-30[media] rc-main: assign driver type during allocationAndi Shyti8-20/+8
The driver type can be assigned immediately when an RC device requests to the framework to allocate the device. This is an 'enum rc_driver_type' data type and specifies whether the device is a raw receiver or scancode receiver. The type will be given as parameter to the rc_allocate_device device. Change accordingly all the drivers calling rc_allocate_device() so that the device type is specified during the rc device allocation. Whenever the device type is not specified, it will be set as RC_DRIVER_SCANCODE which was the default '0' value.

2016-11-25[media] cx88: make checkpatch.pl happyMauro Carvalho Chehab16-872/+975
Usually, I don't like fixing coding style issues on non-staging drivers, as it could be a mess pretty easy, and could become like a snow ball. That's the case of recent changes on two changesets: they disalign some statements. Yet, a care a lot with cx88 driver, as it was the first driver I touched at the Kernel, and I've been maintaining it since 2005. So, several of the coding style issues were due to my code. Per Andrey's suggestion, I ran checkpatch.pl in strict mode, with fixed several other issues, did some function alinments, but broke other alinments. So, I had to manually apply another round of manual fixes to make sure that everything is ok, and to make checkpatch happy with this patch. With this patch, checkpatch.pl is now happy when called with: ./scripts/checkpatch.pl -f --max-line-length=998 --ignore PREFER_PR_LEVEL Also, the 80-cols violations that made sense were fixed. Checkpatch would be happier if we convert it to use dev_foo(), but this is a more complex change. NOTE: there are some places with msleep(1). As this driver was written at the time that the default was to sleep at least 10ms on such calls (e. g. CONFIG_HZ=100), I replaced those calls by usleep_range(10000, 20000), with should be safe to avoid breakages.

This fixes a lockup at device probing which happens on some solo6010 hardware samples. This is a regression introduced by commit e1ceb25a1569 ("[media] SOLO6x10: remove unneeded register locking and barriers") The observed lockup happens in solo_set_motion_threshold() called from solo_motion_config(). This extra "flushing" is not fundamentally needed for every write, but apparently the code in driver assumes such behaviour at last in some places. Actual fix was proposed by Hans Verkuil.

2016-11-16[media] cx88-dsp: Use kmalloc_array() in read_rds_samples()Markus Elfring1-2/+1
* A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software. * Replace the specification of a data type by a pointer dereference to make the corresponding size determination a bit safer according to the Linux coding style convention.
