| 4 | Subject: [PATCH] Fix rpi-eeprom-update when using busybox find |
| 5 | |
| 6 | The busybox implementation of find does not detect recursive nested |
| 7 | symlinks, this results in it finding multiple instances of of_node |
| 8 | matching -samefile, the result of which then fails the -e path test. |
| 9 | |
| 10 | The of_node symlink we're tyring to find should match the path |
| 11 | /sys/bus/nvmem/devices/*/of_node so just limit the find depth to 3 as |
| 12 | there's no point searching deeper than that. |
