From: Wei Yongjun Date: Fri, 15 Mar 2013 09:19:26 +0000 (+0800) Subject: target: fix possible memory leak in core_tpg_register() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0fb889b83186e54c0cfa79516599f2267fb553fb;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git target: fix possible memory leak in core_tpg_register() 'se_tpg->tpg_lun_list' is malloced in core_tpg_register() and should be freed before leaving from the error handling cases, otherwise it will cause memory leak. 'se_tpg' is malloced out of this function, and will be freed if we return error, so remove free for 'se_tpg'.
