Subject: [PATCHv6 06/19] I2C: OMAP: Fix the mismatch of pm_runtime enable and disable
Date: Tue, 10 Apr 2012 16:26:24 +0530	[thread overview]
Message-ID: <1334055397-899-7-git-send-email-shubhrajyoti@ti.com> (raw)
In-Reply-To: <1334055397-899-1-git-send-email-shubhrajyoti@ti.com>

Currently the i2c driver calls the pm_runtime_enable and never
the disable. This may cause a warning when pm_runtime_enable
checks for the count match.Attempting to fix the same by calling
pm_runtime_disable in the error and the remove path.
