From fd8308b42c11ff21cedfb08a73f1d7ff73d72e4c Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 4 Dec 2013 13:49:02 -0300 Subject: [PATCH] [media] omap3isp: Use devm_ioremap_resource() Replace devm_request_mem_region() and devm_ioremap_nocache() with devm_ioremap_resource(). The behaviour remains the same and the code is simplified.
