From 01c59df818001b0bd3a31e2301a92a8c73bccbce Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Sat, 7 Mar 2009 00:48:09 -0300 Subject: [PATCH] V4L/DVB (11178): pvrusb2: Make audio sample rate update into a sub-device broadcast The pvrusb2 driver had previously been using i2c module specific calls to set the sample rate (a long long time ago this was needed). These days it is safe to use a broadcast so let's just broadcast this when communicating audio sample rate to sub-devices.
