From 1cd3c0fa927084549005fc22e54d99684b314f14 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 8 Mar 2009 17:04:38 -0300 Subject: V4L/DVB (11022): zoran/bt819: use new notify functionality. Bt819 needs the parent driver to drive a GPIO pin low and high in order to reset its fifo. Use the new notify callback for this.
