From c221287f8ff4e46fffad11bb2a6bc99442e845be Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 20 Apr 2018 15:52:38 +0100 Subject: [PATCH] hw/arm/fsl-imx*: Don't create "null" chardevs for serial devices MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Following commit 12051d82f004024, UART devices should handle being passed a NULL pointer chardev, so we don't need to create "null" backends in board code. Remove the code that does this and updates serial_hds[]. (fsl-imx7.c was already written this way.)
