* [media] tea575x-tuner: update to latest V4L2 framework requirementsHans Verkuil2012-03-19
| | | | | | | | | | | | | | | | | | | | | | | | The tea575x-tuner module has been updated to use the latest V4L2 framework functionality. This also required changes in the drivers that rely on it. The tea575x changes are: - The drivers must provide a v4l2_device struct to the tea module. - The radio_nr module parameter must be part of the actual radio driver, and not of the tea module. - Changed the frequency range to the normal 76-108 MHz range instead of 50-150. - Add hardware frequency seek support. - Fix broken rxsubchans/audmode handling. - The application can now select between stereo and mono. - Support polling for control events. - Add V4L2 priority handling. And radio-sf16fmr2.c now uses the isa bus kernel framework.

* [media] media: ir-sony-decoder: 15bit function decode fixJames Hogan2012-03-08
| | | | | | | | | | | | | | The raw Sony IR decoder decodes 15bit messages slightly incorrectly. To decode the function number, it shifts the bits right by 7 so that the function is in bits 7:1, masks with 0xFD (0b11111101), and does an 8 bit reverse so it ends up in bits 6:0. The mask should be 0xFE to correspond with bits 7:1 (0b11111110). The old mask had the effect of dropping the MSB of the function number from bit 6, and leaving the LSB of the device number in bit 7.

This is also implied by the v4l2-controls.txt documentation and it is clearly the right thing to do. The only reason this was never noticed before is because we never did this. Only recent changes in ivtv made this error visible because there a third handler layer was added (handler A inherits from handler B which inherits from C, D and E). Without this change handler A only sees the controls owned by handler B and the controls from C, D and E are missing.

* [media] rc/ir-raw: use kfifo_rec_ptr_1 instead of kfifoJames Hogan2012-03-08
| | | | | | | | | | | | | | | | | | | | | Raw IR events are passed to the raw event thread through a kfifo. The size of the event struct is 12 bytes, and space for 512 events is reserved in the kfifo (6144 bytes), however this is rounded down to 4096 bytes (the next power of 2) by __kfifo_alloc(). 4096 bytes is not divisible by 12 therefore if the fifo fills up a third of a record will be written in the end of the kfifo by ir_raw_event_store() because the recsize of the fifo is 0 (it doesn't have records). When this is read by ir_raw_event_thread() a corrupted or partial record will be read, and in the case of a partial record the BUG_ON(retval != sizeof(ev)) gets hit too. According to samples/kfifo/record-example.c struct kfifo_rec_ptr_1 can handle records of a length between 0 and 255 bytes, so change struct ir_raw_event_ctrl to use that instead of struct kfifo.
