Subject: [PATCHv2 07/11] dw_dmac: call .probe after we have a device in place
Date: Thu, 10 Jan 2013 10:53:02 +0200 [thread overview]
Message-ID: <1357807986-4026-8-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1357807986-4026-1-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.
