* [media] m88ds3103: use own reg update_bits() implementationAntti Palosaari2015-10-221-26/+47
| | | | | | | | | | | | | | | Device stopped to tuning some channels after regmap conversion. Reason is that regmap_update_bits() works a bit differently for partially volatile registers than old homemade routine. Return back to old routine in order to fix issue.

* [media] rtl28xxu: fix control message flawsAntti Palosaari2015-10-222-3/+14
| | | | | | | | | | | | | | Add lock to prevent concurrent access for control message as control message function uses shared buffer. Without the lock there may be remote control polling which messes the buffer causing IO errors. Increase buffer size and add check for maximum supported message length.

Moreover if the segment is not outside the firmware file then also we have been returning the garbage.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently vb2 core acquires mmap_sem just around call to __qbuf_userptr(). However since commit f035eb4e976ef5 (videobuf2: fix lockdep warning) it isn't necessary to acquire it so early as we no longer have to drop queue mutex before acquiring mmap_sem. So push acquisition of mmap_sem down into .get_userptr memop so that the semaphore is acquired for a shorter time and it is clearer what it is needed for. Note that we also need mmap_sem in .put_userptr memop since that ends up calling vb2_put_vma() which calls vma->vm_ops->close() which should be called with mmap_sem held. However we didn't hold mmap_sem in some code paths anyway (e.g. when called via vb2_ioctl_reqbufs() -> __vb2_queue_free() -> vb2_dma_sg_put_userptr()) and getting mmap_sem in put_userptr() introduces a lock inversion with queue->mmap_lock in the above mentioned call path. Luckily this whole locking mess will get resolved once we convert videobuf2 core to the new mm helper which avoids the need for mmap_sem in .put_userptr memop altogether.

| * | [media] dvb: Use DVBFE_ALGO_HW where applicableMauro Carvalho Chehab2015-08-223-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dvb_frontend.c core defines a FE_ALGO_HW symbol that it is never used. Also, both cx24123 returns 1 to get_algo() callback instead of using DVBFE_ALGO_HW. Probably, those are some left overs from some code cleanup. Let's stop returning magic numbers and use the proper macro value. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Acked-by: Jonathan Corbet <corbet@lwn.net>
