Subject: [PATCH v2 0/2] firmware: exynos-acpm: read fix & reduce log
 verbosity

While trying to use the ACPM driver, I stubmbled across two issues:

    * acpm_pmic_bulk_read() doesn't return the correct register values
    * superfluous log messages during boot

The patches attached are the result and hopefully self-explanatory.

This driver only exists in linux-next at the moment.

Cheers,
Andre'
