Subject: acpi-cpufreq: De-register CPU notifier and free struct msr on error.
X-Git-Tag: v3.14-rc1~21^2^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=eb8c68ef558e6cba241e7ada54f6b3427cb2bf68;p=pandora-kernel.git

acpi-cpufreq: De-register CPU notifier and free struct msr on error.

If cpufreq_register_driver() fails we would free the acpi driver
related structures but not free the ones allocated
by acpi_cpufreq_boost_init() function. This meant that as
the driver error-ed out and a CPU online/offline event came
we would crash and burn as one of the CPU notifiers would point
to garbage.
