Subject: x86/platform/intel-mid: Correct MSI IRQ line for watchdog device
From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
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:
