From 0e09a3c92bfd54a6ac03f8225c4fd10f50111beb Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 22 Feb 2011 00:10:22 -0300 Subject: [PATCH] [media] tvp5150: device detection should be done only once Having the device detection happening at reset is bad, as every time, it will produce a message like: tvp5150 2-005c: tvp5150am1 detected. This only polutes the log and for an accidental kernel hacker, it looks like a real problem. So, move those printk's to happen during device probe.
