Hmm these I already fixed earlier along with a merge resolution, and
I'm not seeing them in next/master or arm-soc/for-next. What do you
have merged into your current tree?

Neil, care to provide a fix for this? It's from your commit ab37813
(twl4030_charger: Allow charger to control the regulator that feeds it).

> include/linux/thermal.h:254:12: warning: 'thermal_generate_netlink_event' defined but not used

Eduardo, can you fix that one? It seems to be from your commit 8ab3e6a
(thermal: Use thermal zone device id in netlink messages).

Tony
