Anyway, all those errors weren't taken into account by the w1 framework before (see my other patch). Also, the w1 patches are given for the example and could be improved. Part of the reason is the w1 framework itself :-) Antoine -- Antoine Ténart, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
