+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.
