From 55ca589ab9e6e719c1e1f9fc72997d1643d28fe3 Mon Sep 17 00:00:00 2001 From: Allan Xavier Date: Thu, 12 Jan 2023 12:08:55 +0000 Subject: [PATCH] Fix rpi-eeprom-update when using busybox find The busybox implementation of find does not detect recursive nested symlinks, this results in it finding multiple instances of of_node matching -samefile, the result of which then fails the -e path test. The of_node symlink we're tyring to find should match the path /sys/bus/nvmem/devices/*/of_node so just limit the find depth to 3 as there's no point searching deeper than that.
