From ea46c8f774f295c45fac48101d54be347d3d453b Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 24 May 2010 14:33:21 -0700 Subject: [PATCH] dynamic_debug: small cleanup in ddebug_proc_write() This doesn't change behavior at all. In the original code, if nwords was zero then ddebug_parse_query() would return -EINVAL, now we just do it earlier.
