From eb85ab9ab6a1dbd81103a2d3243e893de3680bf9 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Sat, 17 Apr 2021 20:32:57 +0200 Subject: rockchip: use alternative CID path Use an alternative path to access the CID of the SD card in MMC0, used for the generation of MAC addresses. With Kernel 5.10, the device name of the MMC controller changed, breaking MAC address generation. The new path is compatible with Kernel 5.4 as well as Kernel 5.10.
