Subject: [PATCH 01/10] Revert "sh-sci / PM: Avoid deadlocking runtime PM"

From: [email-masked] (Shinya Kuribayashi)
Date: Wed, 07 Nov 2012 15:58:06 +0900

This reverts commit 048be431e4 (sh-sci / PM: Avoid deadlocking runtime
PM, from Rafael J. Wysocki <[email-masked]>, 2012-03-09).

In order to get console PM work properly, we should implement uart_ops
->pm() operation, rather than sprinkle band-ading runtime PM calls in
the driver.
