From: H Hartley Sweeten Date: Tue, 1 Oct 2013 22:11:58 +0000 (-0700) Subject: staging: comedi: ni_6527: rename CamelCase defines for the clear register X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=73261fc0de10b7fcfe6f9d0614f9ce0ee15dbad6;p=linux-beck.git staging: comedi: ni_6527: rename CamelCase defines for the clear register Rename the CamelCase defines used for the clear register. To clarify the code a bit, add two new defines that group the bits needed to clear the interrupts and reset the digital input deglitch filter.
