Subject: [PATCH V2 1/6] pinctrl: pinctrl-single: use arch_initcall and module_exit
Date: Tue, 29 Jan 2013 13:08:49 +0530	[thread overview]
Message-ID: <1359445134-13323-2-git-send-email-manishv.b@ti.com> (raw)
In-Reply-To: <1359445134-13323-1-git-send-email-manishv.b@ti.com>

Currently, I2C driver gets probed before pinctrl driver.
To achieve I2C pin muxing via pinctrl driver before I2C
probe get called, register pinctrl driver in arch_initcall.
Also, add module_exit to unregister pinctrl driver.
