[PATCH v6 02/17] media: v4l2-ioctl: check_ext_ctrls: Return -EINVAL on V4L2_CTRL_WHICH_REQUEST_VAL

[Ricardo Ribalda]

Drivers that do not use the ctrl-framework use this function instead.

- Return -EINVAL for request_api calls

Fixes v4l2-compliance:
Buffer ioctls (Input 0):
                fail: v4l2-test-buffers.cpp(1994): ret != EINVAL && ret != 
EBADR && ret != ENOTTY
        test Requests: FAIL

Cc: sta...@vger.kernel.org
Fixes: 6fa6f831f095 ("media: v4l2-ctrls: add core request support")
