From 0634c2958927198797bf9e55d26fb51cce4c22b4 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 22 Mar 2017 09:16:27 -0500 Subject: of: Add function for generating a DT modalias with a newline The modalias sysfs attr is lacking a newline for DT aliases on platform devices. The macio and ibmebus correctly add the newline, but open code it. Introduce a new function, of_device_modalias(), that fills the buffer with the modalias including the newline and update users of the old of_device_get_modalias function.
