From ba99a0f19ae04820104c1cba11027ec69495879c Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Tue, 22 Mar 2016 22:22:48 +0530 Subject: [PATCH] staging: media: omap1: Replace kzalloc with devm_kzalloc Replace kzalloc with devm_kzalloc and consequently remove kfrees in probe and remove functions of a platform device. As a result of this change, remove unnecessary out of memory message and an unnecessary label.
