[PATCH v2 2/2] uio: add default compatible string to uio_pdrv_genirq

From: Chris Packham
Date: Thu Sep 21 2017 - 11:48:42 EST


Add a default compatible string "linux,uio-pdrv-genirq" to
uio_pdrv_genirq to make it usable without supplying a module parameter.
The module parameter is still supported in addition to the default.
