One which would be nice to fixup is based on the sysfs patch. Another, but not so hurried, is to have cleanup.h management for v4l2 calls. Side note: Since we have many headers to be split from kernel.h (array_size.h, container_of.h, hex.h, kstrtox.h, sprintf.h) consider replacing "proxy" headers in the code. Especially when headers in the driver include kernel.h for peanuts. -- With Best Regards, Andy Shevchenko
