Esben Haabendal 8ef1216a9e uio_pdrv_genirq: fix use without device tree and no interrupt
commit bf12fdf0ab upstream.

While e3a3c3a205 ("UIO: fix uio_pdrv_genirq with device tree but no
interrupt") added support for using uio_pdrv_genirq for devices without
interrupt for device tree platforms, the removal of uio_pdrv in
26dac3c49d ("uio: Remove uio_pdrv and use uio_pdrv_genirq instead")
broke the support for non device tree platforms.

This change fixes this, so that uio_pdrv_genirq can be used without
interrupt on all platforms.

This still leaves the support that uio_pdrv had for custom interrupt
handler lacking, as uio_pdrv_genirq does not handle it (yet).

Fixes: 26dac3c49d ("uio: Remove uio_pdrv and use uio_pdrv_genirq instead")
