From: Roberto Sassu Date: Wed, 27 Nov 2013 13:40:41 +0000 (+0100) Subject: ima: store address of template_fmt_copy in a pointer before calling strsep X-Git-Tag: v3.13-rc3~32 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=af91706d5ddecb4a9858cca9e90d463037cfd498;p=profile%2Fcommon%2Fkernel-common.git ima: store address of template_fmt_copy in a pointer before calling strsep This patch stores the address of the 'template_fmt_copy' variable in a new variable, called 'template_fmt_ptr', so that the latter is passed as an argument of strsep() instead of the former. This modification is needed in order to correctly free the memory area referenced by 'template_fmt_copy' (strsep() modifies the pointer of the passed string).
