Subject: [resend][PATCH 01/16] dw_dmac: call .probe after we have a device in place
Date: Wed,  9 Jan 2013 10:17:00 +0200	[thread overview]
Message-ID: <1357719435-29955-2-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1357719435-29955-1-git-send-email-andriy.shevchenko@linux.intel.com>

If we don't yet have the platform device for the driver when it is being loaded
we fail to probe the driver. So instead of calling probe() directly we call
platform_driver_register(). It will call the probe() immediately if we have the
device but also makes the driver to work on platforms where the platform device
is created later.
