| Patch reverts upstream commit: |
| https://github.com/collectd/collectd/commit/6124da7a48f28f54fc09ebeb942d1037516fe6ab |
| |
| The commit changed the detection path due to FreeBSD issues, |
| but apparently affects also Openwrt buildroot negatively. |
| |
| Original explanation: |

| Subject: [PATCH] Fix libmodbus detection on FreeBSD |
| |
| We look for modbus/modbus.h in /usr/local/include/modbus |
| but we should look for modbus.h |
| |
| This is only an issue on FreeBSD since /usr/local/include is not |
| in the default search path. |
