Here, psscr val is only one u64 ... shouldn't you kmalloc sizeof(..) *
dt_idle_states ?
I'm using kcalloc here since checkpatch script suggested kcalloc over
kzalloc for allocating memory for arrays.
I'll also include a patch to use kcalloc throughout the file for
uniformity in next version. I was originally planning to post that
cleanup separately.
Ah ok, I missed the use of kcalloc (I didn't even know its existence),
my brain just read kmalloc :-)

Still, I find it inconsistent that you allocate here while you use the
stack for the names. Any reason for that ?

Cheers,
Ben.
