thermal: core: Eliminate writable trip points masks All of the thermal_zone_device_register_with_trips() callers pass zero writable trip points masks to it, so drop the mask argument from that function and update all of its callers accordingly. This also removes the artificial trip points per zone limit of 32, related to using writable trip points masks. No intentional functional impact. Signed-off-by: Rafael J.

thermal/core: Use the thermal zone 'devdata' accessor in remaining drivers The thermal zone device structure is exposed to the different drivers and obviously they access the internals while that should be restricted to the core thermal code. In order to self-encapsulate the thermal core code, we need to prevent the drivers accessing directly the thermal zone structure and provide accessor functions to deal with. Use the devdata accessor introduced in the previous patch. No functional changes intended.

thermal/drivers/cxgb4: Use generic thermal_zone_get_trip() function The thermal framework gives the possibility to register the trip points with the thermal zone. When that is done, no get_trip_* ops are needed and they can be removed. Convert ops content logic into generic trip points and register them with the thermal zone.

cxgb4: fix thermal zone device registration When multiple adapters are present in the system, pci hot-removing second adapter leads to the following warning as both the adapters registered thermal zone device with same thermal zone name/type. Therefore, use unique thermal zone name during thermal zone device initialization. Also mark thermal zone dev NULL once unregistered.
