| Subject: [PATCH] x86/platform/intel-mid: Correct MSI IRQ line for watchdog |
| device |
| |
| commit 80354c29025833acd72ddac1ffa21c6cb50128cd upstream. |
| |
| The interrupt line used for the watchdog is 12, according to the official |
| Intel Edison BSP code. |
| |
| And indeed after fixing it we start getting an interrupt and thus the |
| watchdog starts working again: |
