* [media] smipcie: add support for TechnoTrend S2-4200 TwinOlli Salonen2016-05-073-1/+15
| | | | | | | | | | | | | | | Add support for TechnoTrend TT-budget S2-4200 Twin DVB-S2 tuner. The device seems to be rather similar to DVBSky S952 V3. This is a PCIe card with 2 tuners. SMI PCIe bridge is used and the card has two Montage M88RS6000 demod/tuners. The M88RS6000 demod/tuner package needs firmware.

* [media] ati_remote: avoid fragile snprintf useRasmus Villemoes2016-05-071-7/+4
| | | | | | | | | | Passing overlapping source and destination to snprintf is fragile. Replace with a single (mostly) equivalent call. If one wants to preserve the space preceding udev->product whether or not there was a manufacturer, just remove udev->manufacturer from the && expression.

* [media] v4l2-ioctl.c: improve cropcap compatibility codeHans Verkuil2016-05-061-27/+43
| | | | | | | | | | | | | | | | | | | | | - Add a check for the case that both the cropcap and g_selection ops are NULL. This shouldn't happen, but I feel happier if the code guards against this. - If g_selection exists, then ignore ENOTTY and ENOIOCTLCMD error codes from cropcap. Just assume square pixelaspect ratio in that case. This situation can happen if the bridge driver's cropcap op calls the corresponding subdev's op. So the cropcap ioctl is set, but it might return ENOIOCTLCMD anyway. In the past this would just return an error which is wrong. - Call cropcap first and let g_selection overwrite the bounds and defrect. This safeguards against subdev cropcap implementations that set those rectangles as well. What g_selection returns has priority over what such cropcap implementations return.

This polls the PSL to ensure that the PSL is clear of IRQs for the detached context, before removing the context from the idr.

This won't leak IRQs as if we allocate the mapping again, the generic code will give the same mapping used last time. Doing this works around a race in the generic code. Masking the interrupt introduces a race which can crash the kernel or result in IRQ that is never EOIed. The lost of EOI results in all subsequent mappings to the same HW IRQ never receiving an interrupt. We've seen this race with cxl test cases which are doing heavy context startup and teardown at the same time as heavy interrupt load. A fix to the generic code is being investigated also.

This can lead to hotplugging breaking (along with probably other things) since the hub will start sending connection notifications with the wrong GUID. As such, we need to check on resume whether or not the GUID the hub is giving us is valid.
