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. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
