[linux-yocto] [PATCH 1/4] mmc: block: Always switch back to main area after RPMB access
From: Adrian Hunter commit 3c866568aff7dcfc0bbd5ffc7fcc34fa8f100f67 upstream. In preparation to support the use of the RPMB partition with transfer modes that might require re-tuning, always switch back to the main area after RPMB access. RPMB is accessible only via IOCTL so only those paths are affected.

Sorry for the spam, but ignore these.
