Subject: [PATCH 5.10 704/717] memory: renesas-rpc-if: Fix unbalanced pm_runtime_enable in rpcif_{enable,disable}_rpm

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

commit 61a6d854b9555b420fbfae62ef26baa8b9493b32 upstream.

rpcif_enable_rpm calls pm_runtime_enable, so rpcif_disable_rpm needs to
call pm_runtime_disable and not pm_runtime_put_sync.

Fixes: ca7d8b980b67f ("memory: add Renesas RPC-IF driver")
