From d1fd3ddc469b576e36184f2bd02c0301d80118d3 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 7 May 2013 12:32:16 -0700 Subject: [PATCH] drm: refactor call to request_module This reduces the size of the stack frame when calling request_module(). Performing the sprintf before the call is not needed.
