From e5f376df8b13cf09220a8003469b10a9b8095d3c Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 19 Feb 2014 10:11:22 -0700 Subject: [PATCH] staging: comedi: pcl816: clarify irq request in pcl816_attach() All the board types can use IRQ 2-7 for async command support. Remove the 'IRQbits', which is a mask of the valid IRQs, from the boardinfo and refactor pcl816_attach().
