To support loading of a layout module automatically the MODALIAS variable in the uevent is needed. Add it.

Fixes: fc29fd821d9a ("nvmem: core: Rework layouts to become regular devices") Cc: stable@vger.kernel.org Signed-off-by: Michael Walle mwalle@kernel.org --- I'm still not sure if the sysfs modalias file is required or not. It seems to work without it. I could't find any documentation about it.
