[PATCH 1/9] staging: fsl-dpaa2/eth: Use generic irq handler

Ioana Radulescu
2018-03-23T13:44:05Z

For the link state interrupt, we used a dummy non-threaded
irq handler, which had the same implementation as the generic
irq_default_primary_handler() function.

Give up on using our own irq handler and let the kernel use
the generic one instead.
