Subject[PATCH v2 1/2] powerpc/powernv: rename remaining rng powernv_ functions to pnv_
Date
The preferred nomenclature is pnv_, not powernv_, but rng.c used
powernv_ for some reason, which isn't consistent with the rest. A recent
commit added a few pnv_ functions to rng.c, making the file a bit of a
mishmash. This commit just replaces the rest of them.

Cc: Michael Ellerman <mpe@ellerman.id.au>
Fixes: f3eac426657 ("powerpc/powernv: wire up rng during setup_arch")
