Subject: ARM: at91: standard device init only if DT is not populated.
X-Git-Tag: Ubuntu-5.10.0-12.13~21461^2~4^2~6
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=8cf93b9ceaf4534cdeda5727782001f8fecb1688;p=mirror_ubuntu-hirsute-kernel.git

ARM: at91: standard device init only if DT is not populated.

This will avoid the CONFIG_OF on the *_devices.c as this file is deprecated
for DT support.
