Subject: [PATCH 4/9] i2c: i2c-stu300: replace platform_driver_probe to support deferred probing
Date: Tue,  8 Oct 2013 22:35:36 +0200	[thread overview]
Message-ID: <1381264542-29396-5-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1381264542-29396-1-git-send-email-wsa@the-dreams.de>

Subsystems like pinctrl and gpio rightfully make use of deferred probing at
core level. Now, deferred drivers won't be retried if they don't have a .probe
function specified in the driver struct. Fix this driver to have that, so the
devices it supports won't get lost in a deferred probe.
