[media] dib8000: Fix the sleep time at the state machine
msleep() is not too precise: its precision depends on the HZ config. As the driver selects precise timings for the state machine, change it to usleep_range(). Acked-By: Patrick Boettcher <pboettcher@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
