    thermal: db8500_cpufreq_cooling: remove usage of IS_ERR_OR_NULL() · 70d23b29
    Eduardo Valentin authored
    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().
