2017-07-26media: pulse8-cec: persistent_config should be off by defaultHans Verkuil
The persistent_config option is used to make the CEC settings persistent by using the eeprom inside the device to store this information. This was on by default, which caused confusion since this device now behaves differently from other CEC devices which all come up unconfigured. Another reason for doing this now is that I hope a more standard way of selecting persistent configuration will be created in the future. And for that to work all CEC drivers should behave the same and come up unconfigured by default. None of the open source CEC applications are using this CEC framework at the moment so change this behavior before it is too late.

As reported by this warning: drivers/media/usb/pvrusb2/pvrusb2-encoder.c:263 pvr2_encoder_cmd() warn: continue to end of do { ... } while(0); loop There's an issue at the retry logic there: the current logic is: do { if (need_to_retry) continue; some_code(); } while (0); Well, that won't work, as continue will make it test for zero, and abort the loop. So, change the loop to: while (1) { if (need_to_retry) continue; some_code(); break; }; With seems to be what's actually expected there.

While testing support for Terratec H6 rev. 2, it was noticed that reading from eeprom there causes a timeout error. Apparently, this is due to the need of properly setting GPIOs.

Permits distinguishing between two /dev/videoX entries from the same physical UVC device (that naturally share the same iProduct name). This change matches current Windows behavior by prioritizing iFunction over iInterface, but unlike Windows it displays both iProduct and iFunction/iInterface strings when both are available.

2017-06-06[media] mxl111sf: Fix driver to use heap allocate buffers for USB messagesDevin Heitmueller
The recent changes in 4.9 to mandate USB buffers be heap allocated broke this driver, which was allocating the buffers on the stack. This resulted in the device failing at initialization. Introduce dedicated send/receive buffers as part of the state structure, and add a mutex to protect access to them. Note: we also had to tweak the API to mxl111sf_ctrl_msg to pass the pointer to the state struct rather than the device, since we need it inside the function to access the buffers and the mutex. This patch adjusts the callers to match the API change.

2017-06-04[media] cec: select CEC_CORE instead of depend on itHans Verkuil
The CEC framework is used by both drm and media. That makes it tricky to get the dependencies right. This patch moves the CEC_CORE and MEDIA_CEC_NOTIFIER config options out of the media menu and instead drivers that want to use CEC should select CEC_CORE and MEDIA_CEC_NOTIFIER (if needed).

2017-05-19[media] s2255drv: avoid a switch fall throughMauro Carvalho Chehab
On this driver, it can fall through a switch. I tried to annotate it, in order to shut up a gcc warning, but that didn't work, as the logic there is somewhat complex. So, instead, let's just repeat the code. gcc should likely optimize it anyway, and this makes the code better readable, IMHO. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
