What's odd is that there is an explicit select on RESET_CONTROLLER in the Kconfig. Maybe it's the circular dependency issue that has been reported that cause this and Wolfram sent a patch for: http://patchwork.ozlabs.org/patch/327573/ Maxime -- Maxime Ripard, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com -------------- next part -------------- A non-text attachment was scrubbed...
