From 6428832a7bfae73345706d63a228a6ce60af0081 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Wed, 27 May 2015 16:07:07 +1000 Subject: [PATCH] cxl: Add cookie parameter to afu_release_irqs() Add cookie parameter to afu_release_irqs() so that we can pass in a different cookie than the context structure. This will be useful for other kernel drivers that want to call this but get their own cookie back in the interrupt handler. Update all existing call sites.
