Converts the dtt200u DVB USB driver over to the rc-core infrastructure for its handling of IR remotes. This device can receive generic NEC / NEC Extended signals and the switch to the newer core enables the easy use of tools such as ir-keytable to modify the active key map. Signed-off-by:

Fix RC5 decoding with Fintek CIR chipset Commit e87b540b tightened up the RC5 decoding by adding a check for trailing silence to ensure a valid RC5 command had been received. Unfortunately the trailer length checked was 10 units and the Fintek CIR device does not want to provide details of a space longer than 6350us. This meant that RC5 remotes working on a Fintek setup on 3.16 failed on 3.17 and later. Fix this by shortening the trailer check to 6 units (allowing for a previous space in the received remote command). Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=117221Signed-off-by:

Implement memory barriers according to Documentation/circular-buffers.txt: - use smp_store_release() to update ringbuffer read/write pointers - use smp_load_acquire() to load write pointer on reader side - use ACCESS_ONCE() to load read pointer on writer side This fixes data stream corruptions observed e.g. on an ARM Cortex-A9 quad core system with different types (PCI, USB) of DVB tuners.

The workqueue "work_thread" is involved in updating parameters for transfers. It has a single work item(&sd->work) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. Work item has been flushed in sd_stop0() to ensure that there are no pending tasks while disconnecting the driver. Signed-off-by:

The current code will expose a zero value if one of the stats is not available, but this is not what userspace expects. Instead, if something goes wrong on providing some stats, it should be changing the scale to FE_SCALE_NOT_AVAILABLE. So, change the logic to do the right thing. Signed-off-by: -

The signal strength value is reversed: the bigger the number, the weaker is the signal. Fix the logic and present it in dBm. Please notice that the dBm measure is actually an estimation, as the ratio is not fully linear. It also varies with the frequency. Yet, the estimation should be good enough for programs like Kaffeine to indicate when the signal is good or bad. Signed-off-by:

Mauro Carvalho Chehab authored
It is a good idea to measure the signal strength while tuning, as this helps to identify if the antenna is ok. Also, such measure helps to identify the quality of the signal. Do some changes to enable it before signal lock. While here, optimize the code to only initialize the stats length once, and make sure that, just after set_frontend, any reading for the stats that depends on lock to return FE_SCALE_NOT_AVAILABLE.

- Use IS_REACHABLE(RC_CORE) instead of IS_ENABLED: if cec is built-in and RC_CORE is a module, then CEC can't reach the RC symbols. - Both cec and cec-edid should be bool and use the same build 'mode' as MEDIA_SUPPORT (just as is done for the media controller code). - Add a note to staging that this should be changed once the cec framework is moved out of staging.

The MEDIA_CEC_EDID option is guarded by MEDIA_SUPPORT, so selecting it from MEDIA_CEC produces a warning: warning: (MEDIA_CEC) selects MEDIA_CEC_EDID which has unmet direct dependencies (MEDIA_SUPPORT) The warning is harmless, but it's better to add an explicit dependency to shut it up, to reduce the noise during randconfig builds.

The suspend/resume functions in the s5p-cec driver are only referenced when CONFIG_PM is enabled, so we get a warning about unused functions otherwise: drivers/staging/media/s5p-cec/s5p_cec.c:260:12: error: 's5p_cec_resume' defined but not used [-Werror=unused-function] static int s5p_cec_resume(struct device *dev) ^~~~~~~~~~~~~~ drivers/staging/media/s5p-cec/s5p_cec.c:253:12: error: 's5p_cec_suspend' defined but not used [-Werror=unused-function] static int s5p_cec_suspend(struct device *dev) This marks them as __maybe_unused to avoid the warning without having to introduce an extra #ifdef.

CEC_MSG_REPORT_PHYSICAL_ADDR can theoretically be received from an unregistered device, but in that case the code should not attempt to write the received physical address to the phys_addrs array. That would be pointless since there can be multiple unregistered devices that report a physical address. We just ignore those. While at it, improve the dprintk since it would attempt to read from that array as well with the same out-of-bounds problem. Signed-off-by:
