Subject: [PATCH] move q40fb's probe function to .devinit.text
Date: Mon, 12 Jan 2009 23:24:45 +0100 [thread overview]
Message-ID: <1231799107-20136-40-git-send-email-u.kleine-koenig@pengutronix.de> (raw)
In-Reply-To: <S1757830AbZALWQu/20090112221650Z+1710@vger.kernel.org>
A pointer to q40fb_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.
