[patch v1]rtc: fix for DA9052/53 rtc device registration

[Ashish Jangam]

Without this patch rtc device will fail in registration.

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read Documentation/stable_kernel_rules.txt
for how to do this properly.

This patch is the -stable counterpart of
http://ozlabs.org/~akpm/mmots/broken-out/drivers-rtc-rtc-da9052c-fix-for-rtc-device-registration.patch,
which I'll be sending Linuswards tomorrow, I expect.

So you'll be looking for this patch pretty soon!
