Subject: DM9000_IRQ_FLAGS
Date: Tue, 11 Dec 2007 20:18:23 +0100	[thread overview]
Message-ID: <20071211191823.GD15295@buzzloop.caiaq.de> (raw)

Hi,

on Toradex' Colibri, a PXA270 based board with a DM9000 ethernet
controller, this driver won't work due to unsuitable DM9000_IRQ_FLAGS.
If I understood the code behind request_irq() correctly, it's not
recommended to register an IRQ without any of the IRQT_* flags set.

Is there any concerns about applying the patch below?

Best regards,
Daniel
