From 9dc53852b10888f9032baf78d672b45ab4d791fe Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Fri, 20 May 2016 14:49:13 +0100 Subject: [PATCH] staging: comedi: drivers: re-do PLX PCI 9080 INTCSR register values Replace the existing macros in "plx9080.h" that define values for the INTCSR register. Use the prefix `PLX_INTCSR_` for the macros. Make use of the `BIT(x)` and `GENMASK(h,l)` macros to define the values.
