[PATCH] kernel spams syslog every 10 sec with w1 debug

[Olaf Hering]

Bug 104020 - kernel spams syslog every 10 sec with: w1_driver w1_bus_master1: No devices present on the wire.

After installing 10.0 B1, I found this in my syslog: 
Aug 10 23:40:06 linux kernel: w1_driver w1_bus_master1: No devices present on the wire. 
Aug 10 23:40:16 linux kernel: w1_driver w1_bus_master1: No devices present on the wire.
