Re: [PATCH] acpi-cpufreq: De-register cpu notifier and free struct msr on error.

On 28 January 2014 09:28, Konrad Rzeszutek Wilk [off-list ref] wrote:

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.

This fixes a regression that commit cfc9c8ed03e4d908f2388af8815f44c87b503aaf
"acpi-cpufreq: Adjust the code to use the common boost attribute"
introduced.
