| Subject: MIPS: AR7: Ensure that serial ports are properly set up |
| |
| From: Oswald Buddenhagen <oswald.buddenhagen@gmx.de> |
| |
| commit b084116f8587b222a2c5ef6dcd846f40f24b9420 upstream. |
| |
| Without UPF_FIXED_TYPE, the data from the PORT_AR7 uart_config entry is |
| never copied, resulting in a dead port. |
