From a59388668d0ce19dadea909e09f4eb905a27b1ce Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Wed, 8 Jun 2016 12:08:43 +0200 Subject: [PATCH] serial/bcm63xx_uart: use correct alias naming The bcm63xx_uart driver uses the of alias for determing its id. Recent changes in dts files changed the expected 'uartX' to the recommended 'serialX', breaking serial output. Fix this by checking for a 'serialX' alias as well.
