2014-07-26[media] media: dvb-core move fe exit flag from fepriv to fe for driver accessShuah Khan
Some fe drivers attempt to access the device for power control from their release routines. When release routines are called after device is disconnected, the attempts fail. fe drivers should avoid accessing the device, from their release interfaces when called from disconnect path. dvb-frontend maintains exit flag to keep track when fe device is disconnected in its private data structures. Export the flag in fe to enable drivers to check the device status from their release interfaces.

2014-07-26[media] media: em28xx - remove reset_resume interfaceShuah Khan
em28xx uses resume interface as its reset_resume interface. If usb device is reset during suspend, reset_resume doesn't do the necessary initialization which leads to resume failure. Many systems don't maintain do not maintain suspend current to the USB host controllers during hibernation. Remove reset_resume to allow disconnect to be called followed by device restore sequence.

2014-07-25[media] ati_remote: Better default keycodesGeorge Spelvin
This tries to make them more like other remotes, and/or the button labels. Notably, the (>>) button is made KEY_FASTFORWARD, which is the correct opposite of (<<)'s KEY_REVERSE. (It was KEY_FORWARD, something else entirely.) Likewise, KEY_STOP is the Sun keyboard "interrupt program" key; the media key is KEY_STOPCD. A restriction is that I try to avoid keycodes above 255, as the X11 client/server protocol is limited to 8-bit key codes. If not for this, I would have used the KEY_NUMERIC_x codes for the numbers.

2014-07-25[media] rc-core: merge rc5 and streamzap decodersDavid Härdeman
Now that the protocol is part of the scancode, it is pretty easy to merge the rc5 and streamzap decoders. An additional advantage is that the decoder is now stricter as it waits for the trailing silence before determining that a command is a valid rc5/streamzap command (which avoids collisions that I've seen with e.g. Sony protocols).

The basic API of rc-core used to be: dev = rc_allocate_device(); dev->x = a; dev->y = b; dev->z = c; rc_register_device(); which is a pretty common pattern in the kernel, after the introduction of protocol arrays the API looks something like: dev = rc_allocate_device(); dev->x = a; rc_set_allowed_protocols(dev, RC_BIT_X); dev->z = c; rc_register_device(); There's no real need for the protocols to be an array, so change it back to be consistent (and in preparation for the following patches).

2014-07-23[media] dib0700: NEC scancode cleanupDavid Härdeman
the RC RX packet is defined as: struct dib0700_rc_response { ... u8 not_system; u8 system; ... u8 data; u8 not_data; The NEC protocol transmits in the order: system not_system data not_data Note that the code defines the NEC extended scancode as: scancode = be16_to_cpu(poll_reply->system16) << 8 | poll_reply->data; i.e. scancode = poll_reply->not_system << 16 | poll_reply->system << 8 | poll_reply->data; Which, if the order *is* reversed, would mean that the scancode that gets defined is in reality: scancode = poll_reply->system << 16 | poll_reply->not_system << 8 | poll_reply->data; Which is the same as the order used in drivers/media/rc/ir-nec-decoder.c.
