      thermal: core: Rework thermal zone availability check · b38aa87f
      Rafael J. Wysocki authored
      
      
      In order to avoid running __thermal_zone_device_update() for thermal
      zones going away, the thermal zone lock is held around device_del()
      in thermal_zone_device_unregister() and thermal_zone_device_update()
      passes the given thermal zone device to device_is_registered().
      This allows thermal_zone_device_update() to skip the
      __thermal_zone_device_update() if device_del() has already run for
      the thermal zone at hand.
      
      However, instead of looking at driver core internals, the thermal
      subsystem may as well rely on its own data structures for this
      purpose.  Namely, if the thermal zone is not present in
      thermal_tz_list, it can be regarded as unavailable, which in fact is
      already the case in thermal_zone_device_unregister().  Accordingly,
      the device_is_registered() check in thermal_zone_device_update() can
      be replaced with checking whether or not the node list_head in struct
      thermal_zone_device is empty, in which case it is not there in
      thermal_tz_list.
      
      To make this work, though, it is necessary to initialize tz->node
      in thermal_zone_device_register_with_trips() before registering the
      thermal zone device and it needs to be added to thermal_tz_list and
      deleted from it under its zone lock.
      
      After the above modifications, the zone lock does not need to be
      held around device_del() in thermal_zone_device_unregister() any more.

      thermal: Drop redundant and confusing device_is_registered() checks · c3ffdfff
      Rafael J. Wysocki authored
      
      
      Multiple places in the thermal subsystem (most importantly, sysfs
      attribute callback functions) check if the given thermal zone device is
      still registered in order to return early in case the device_del() in
      thermal_zone_device_unregister() has run already.
      
      However, after thermal_zone_device_unregister() has been made wait for
      all of the zone-related activity to complete before returning, it is
      not necessary to do that any more, because all of the code holding a
      reference to the thermal zone device object will be waited for even if
      it does not do anything special to enforce this.
      
      Accordingly, drop all of the device_is_registered() checks that are now
      redundant and get rid of the zone locking that is not necessary any more
      after dropping them.

      thermal: core: Make thermal_zone_device_unregister() return after freeing the zone · 4649620d
      Rafael J. Wysocki authored
      
      
      Make thermal_zone_device_unregister() wait until all of the references
      to the given thermal zone object have been dropped and free it before
      returning.
      
      This guarantees that when thermal_zone_device_unregister() returns,
      there is no leftover activity regarding the thermal zone in question
      which is required by some of its callers (for instance, modular driver
      code that wants to know when it is safe to let the module go away).
      
      Subsequently, this will allow some confusing device_is_registered()
      checks to be dropped from the thermal sysfs and core code.

      thermal: sysfs: Rework the reading of trip point attributes · 18dfb0e4
      Rafael J. Wysocki authored
      
      
      Rework the _show() callback functions for the trip point temperature,
      hysteresis and type attributes to avoid copying the values of struct
      thermal_trip fields that they do not use and make them carry out the
      same validation checks as the corresponding _store() callback functions.
      
      No intentional functional impact.

      thermal: sysfs: Rework the handling of trip point updates · be0a3600
      Rafael J. Wysocki authored
      
      
      Both trip_point_temp_store() and trip_point_hyst_store() use
      thermal_zone_set_trip() to update a given trip point, but none of them
      actually needs to change more than one field in struct thermal_trip
      representing it.  However, each of them effectively calls
      __thermal_zone_get_trip() twice in a row for the same trip index value,
      once directly and once via thermal_zone_set_trip(), which is not
      particularly efficient, and the way in which thermal_zone_set_trip()
      carries out the update is not particularly straightforward.
      
      Moreover, input processing need not be done under the thermal zone lock
      in any of these functions.
      
      Rework trip_point_temp_store() and trip_point_hyst_store() to address
      the above, move the part of thermal_zone_set_trip() that is still
      useful to a new function called thermal_zone_trip_updated() and drop
      the rest of it.
      
      While at it, make trip_point_hyst_store() reject negative hysteresis
      values.

      strlcpy() reads the entire source buffer first. This read may exceed
      the destination size limit. This is both inefficient and can lead
      to linear read overflows if a source string is not NUL-terminated[1].
      Additionally, it returns the size of the source string, not the
      resulting size of the destination string. In an effort to remove strlcpy()
      completely[2], replace strlcpy() here with strscpy().
