Currently stk1160_read_reg() uses a stack-allocated char to get the read control value. This is wrong because usb_control_msg() requires a kmalloc-ed buffer. This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive the read value. While here, let's remove the urb_buf array which was meant for a similar purpose, but never really used.

This patch removes some modprobe parameters, without any reason or description. I was supposed to not merge this patch, but It was merged by mistake. Revert it while nobody provides a good description for such patch. This reverts commit b952662f.

This event indicates that the video device has encountered a source parameter change during runtime. This can typically be a resolution change detected by a video decoder OR a format change detected by an input connector. This needs to be nofified to the userspace and the application may be expected to reallocate buffers before proceeding. The application can subscribe to events on a specific pad or input port which it is interested in. Signed-off-by:

There is a few conflicts with older symbols on older kernels so we have to patch this driver when backporting. Instead just make these routines specific to the driver. Signed-off-by:

The current names clash with include/linux/leds.h namespace, although there is no compile issue currently this does affect backports. Drivers should also try to avoid generic namespaces for things like this. Cc: Felipe Pena <felipensp@gmail.com> Cc: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by:
