From 89dab3573aa1d95fd222ee4551f964bfa4c16823 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 7 Jan 2008 06:46:26 -0200 Subject: [PATCH] V4L/DVB (6916): ivtv: udelay has to be changed *after* the eeprom was read, not before The eeprom decides which Hauppauge model it is, so the decision whether to use an udelay of 5 or 10 needs to be taken after reading the eeprom, not before.
