From 80ccf4ad06dc9d2f06a8347b2d309cdc959f72b3 Mon Sep 17 00:00:00 2001 From: Sifan Naeem Date: Tue, 10 Feb 2015 07:41:56 -0300 Subject: [PATCH] [media] rc: img-ir: fix error in parameters passed to irq_free() img_ir_remove() passes a pointer to the ISR function as the 2nd parameter to irq_free() instead of a pointer to the device data structure. This issue causes unloading img-ir module to fail with the below warning after building and loading img-ir as a module.
