Subject: w1: fix slave selection on big-endian systems
From: Evgeniy Polyakov <johnpol@xxxxxxxxxxx>
During test of the w1-gpio driver i found that in "w1.c:679
w1_slave_found()" the device id is converted to little-endian with
"cpu_to_le64()", but its not converted back to cpu format in "w1_io.c:293
w1_reset_select_slave()".
Based on a patch created by Andreas Hummel.
