* media: uvcvideo: Use internal kernel integer typesLaurent Pinchart2018-02-23
| | | | | | | | | Replace the __[su]{8,16,32} variant of integer types with the non-underscored types as the code is internal to the driver, not exposed to userspace. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
* media: uvcvideo: Stream error events carry no dataLaurent Pinchart2017-12-08
| | | | | | | | | | According to the UVC specification, stream error events carry no data. Fix a buffer overflow (that should be harmless given data alignment) when reporting the stream error event by removing the data byte from the message.

* [media] uvcvideo: Fix open/close race conditionLaurent Pinchart2013-06-08
| | | | | | | | | | | | | Maintaining the users count using an atomic variable makes sure that access to the counter won't be racy, but doesn't serialize access to the operations protected by the counter. This creates a race condition that could result in the status URB being submitted multiple times. Use a mutex to protect the users count and serialize access to the status start and stop operations.
