Subject: [PATCH] thermal: power_allocator: allocate with kcalloc what you free with kfree

Commit cf736ea6f902 ("thermal: power_allocator: do not use devm*
interfaces") forgot to change a devm_kcalloc() to just kcalloc(), but
it's corresponding devm_kfree() was changed to kfree().  Allocate with
kcalloc() to match the kfree().

Can this be merged for 4.2, please?  I'm having memory problems with
4.2-rc8 because of this.
