From 6d00376ad15a931d4b148e52d80abc54173e9bf5 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 23 Mar 2011 21:21:53 +0800 Subject: crypto: caam - ARRAY_SIZE() vs sizeof() ARRAY_SIZE() was intended here instead of sizeof(). sizeof() is four times larger than ARRAY_SIZE(). outstr is normally 256 chars so printing garbage to it could overfill the buffer and corrupt memory.
