Subject: [PATCH 5/6] phy: omap-usb2: Balance pm_runtime_enable() on probe failure
Date: Wed, 2 Jul 2014 15:03:57 +0300 [thread overview]
Message-ID: <1404302638-3003-6-git-send-email-rogerq@ti.com> (raw)
In-Reply-To: <1404302638-3003-1-git-send-email-rogerq@ti.com>
If probe fails then we need to call pm_runtime_disable() to balance
out the previous pm_runtime_enable() call. Else it will cause
unbalanced pm_runtime_enable() call in the succeding probe call.
This anomaly was observed when the call to devm_phy_create() failed
with -EPROBE_DEFER.
