2011-05-20[media] drxd: provide ability to control rs byteDevin Heitmueller
Provide the ability for the board configuration to specify whether to insert the RS byte into the TS interconnect to the bridge, while not required for the ngene in fact is required for the em28xx.

2011-05-20[media] xc5000: Improve it to work better with 6MHz-spaced channelsMauro Carvalho Chehab
Brazil uses 6MHz-spaced channels. So, the nyquist filter for DVB-C should be different, otherwise, inter-channel interference may badly affect the device, and signal may not be properly decoded. On my tests here, without this patch, sometimes channels are seen, but, most of the time, PID filter returns with timeout. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-05-20drm/radeon/kms: bail early for eDP in hotplug callbackAlex Deucher

2011-05-20drm/radeon/kms: simplify hotplug handler logicAlex Deucher
In the hotplug handler, just use the drm dpms functions. If the monitor is plugged in, turn it on, if it's not, turn it off. This also reduces power usage by turning off the encoder and crtc when the monitor is unplugged. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-05-20drm/radeon/kms: fix up DP clock programming on DCE4/5Alex Deucher
In DP mode, the DP ref clock can come from PPLL, DCPLL, or ext clock, depending on the asic. The crtc virtual pixel clock is derived from the DP ref clock. - DCE4: PPLL or ext clock - DCE5: DCPLL or ext clock Setting ATOM_PPLL_INVALID will cause SetPixelClock to skip PPLL/DCPLL programming and only program the DP DTO for the crtc virtual pixel clock.

2011-05-20HID: hiddev: fix race between hiddev_disconnect and hiddev_releaseJiri Kosina
When hiddev_disconnect() runs with chardev open, it will proceed with usbhid_close(). When userspace in parallel runs the hiddev_release(), it sees !hiddev->exists (as it has been already set so by hiddev_disconnect()) and kfrees hiddev while hiddev_disconnect() hasn't finished yet. Serialize the access to hiddev->exists and hiddev->open by existancelock. Reported-by: mike-@cinci.rr.com Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-05-20HID: magicmouse: ignore 'ivalid report id' while switching modesJiri Kosina
The device reponds with 'invalid report id' when feature report switching it into multitouch mode is sent to it. This has been silently ignored before 0825411ade ("HID: bt: Wait for ACK on Sent Reports"), but since this commit, it propagates -EIO from the _raw callback . So let the driver ignore -EIO as response to 0xd7,0x01 report, as that's how the device reacts in normal mode. Sad, but following reality.
