From d1a470fbd987b28e64287718917faf8caf67a055 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Tue, 20 Jan 2009 14:56:20 -0300 Subject: V4L/DVB (10288): af9015: bug fix: stick does not work always when plugged First control messages to the stick timeouts very often due to probable hw bug. Repeat first message few times if it fails as workaround.
