Subject: Merge with upstream to accommodate with thermal changes
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e6db06a53b1dcf4e9da4aba143e2eb4d63418abb;p=deliverable%2Flinux.git

Merge ... upstream to accommodate with thermal changes

This merge is performed to take commit c56f5c0342dfee11a1 ("Thermal: Make
Thermal trip points writeable") out of Linus' tree and then fixup power
supply class. This is needed since thermal stuff added a new argument:

  CC      drivers/power/power_supply_core.o
drivers/power/power_supply_core.c: In function ‘psy_register_thermal’:
drivers/power/power_supply_core.c:204:6: warning: passing argument 3 of ‘thermal_zone_device_register’ makes integer from pointer without a cast [enabled by default]
include/linux/thermal.h:154:29: note: expected ‘int’ but argument is of type ‘struct power_supply *’
drivers/power/power_supply_core.c:204:6: error: too few arguments to function ‘thermal_zone_device_register’
include/linux/thermal.h:154:29: note: declared here
make[1]: *** [drivers/power/power_supply_core.o] Error 1
make: *** [drivers/power/] Error 2
