From 410ca6053e3c216b8ca0b05f45d6cd76b334a459 Mon Sep 17 00:00:00 2001 From: "Lad, Prabhakar" Date: Mon, 17 Jun 2013 11:20:44 -0300 Subject: [PATCH] [media] media: davinci: vpif_capture: move the freeing of irq and global variables to remove() Ideally the freeing of irq's and the global variables needs to be done in the remove() rather than module_exit(), this patch moves the freeing up of irq's and freeing the memory allocated to channel objects to remove() callback of struct platform_driver.
