2013-05-18drivers/thermal: don't check resource with devm_ioremap_resourceWolfram Sang
devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2013-04-27thermal: db8500_cpufreq_cooling: remove usage of IS_ERR_OR_NULL()Eduardo Valentin
This patch changes the driver to avoid the usage of IS_ERR_OR_NULL() macro. This macro can lead to dangerous results, like returning success (0) during a failure scenario (NULL pointer handling). The case present in this driver can be translated to a simple check for IS_ERR(), as the cpufreq_cooling_register() returns either a valid pointer or an ERR_PTR().

2013-04-27thermal: thermal_core: remove usage of IS_ERR_OR_NULLEduardo Valentin
This patch changes the driver to avoid the usage of IS_ERR_OR_NULL() macro. This macro can lead to dangerous results, like returning success (0) during a failure scenario (NULL pointer handling). The case present in this patch has simply be translated to normal check for NULL and if the pointer has an error code. The later case is needed because functions like thermal_zone_get_zone_by_name() could return an ERR_PTR().

This patch adds a helper function to get a reference of a thermal zone, based on the zone type name. It will perform a zone name lookup and return a reference to a thermal zone device that matches the name requested. In case the zone is not found or when several zones match same name or if the required parameters are invalid, it will return the corresponding error code (ERR_PTR).
