Message-Id: <1433525435-12986-16-git-send-email-abbotti@mev.co.uk> Date: Fri, 5 Jun 2015 18:30:18 +0100 From: Ian Abbott <abbotti@....co.uk> To: <driverdev-devel@...uxdriverproject.org> Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Ian Abbott <abbotti@....co.uk>, H Hartley Sweeten <hsweeten@...ionengravers.com>, <linux-kernel@...r.kernel.org> Subject: [PATCH 15/32] staging: comedi: das08: rename and rewrite DAS08_INTE The `DAS08_INTE` macro contains a mask for the "INTE" bit in the control register (except on "JR" boards). Setting it to 1 enables interrupts. Setting it to 0 disables interrupts and clears the "IRQ" bit in the status register. Rename the macro to `DAS08_CONTROL_INTE` and add a comment. Also use the `BIT()` macro to define its value. (Note: the driver does not currently enable interrupts.)
