s5k83a sensor mounted on many acer laptops have a swiwel allowing it to be rotated. When the camera is in its rotated state, the image needs to be flipped. The only way to check for if the camera has been flipped is to continously poll a register in the m5602. This patch creates a kernel thread which does this. This patch renames some v4l2 ctrls and finally implements a cache in order to prevent unnecessary sensor reads.

After enabling hardware flow control, any subsequent termios call may hang
waiting for the transmitter to drain.  This appears to be caused by a
busy-loop in set_termios() waiting for the transmitter to become empty,
which may take a very long time (or hang indefinitely) if the device at
the other end is blocking us.

A quick look through the tty and serial_core code indicates that any
necessary flushing (which is optional) has already been done at this
point, so there's no need for the driver to flush the transmitter on its
own.

Fix it by removing the busy-loop altogether.
