From c7b87f3d5037a35b5c7bb916ffc826be3fcb208d Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 10 May 2007 16:46:13 +0100 Subject: [ARM] ecard: add helper function for setting ecard irq ops Rather than having every driver fiddle about setting its private IRQ operations and data, provide a helper function to contain this functionality in one place. Arrange to remove the driver-private IRQ operations and data when the device is removed from the driver, and remove the driver private code to do this. This fixes potential problems caused by drivers forgetting to remove these hooks.
