From 6fb73d771159f2d1c9936d769ee42b3a7be3086a Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Sun, 21 Jan 2007 22:44:03 -0600 Subject: pvrusb2: Add comment for why G_TUNER only looks at index zero From: Mike Isely Mauro and I had fixed this bug at the same time. It's a silly one-liner, but my version of the fix included a comment explaining why it was needed. So I'm putting up this version of the fix.
