John Garry 0b0cf6af3f crypto: hisilicon - Fix reference after free of memories on error path ... coccicheck currently warns of the following issues in the driver: drivers/crypto/hisilicon/sec/sec_algs.c:864:51-66: ERROR: reference preceded by free on line 812 drivers/crypto/hisilicon/sec/sec_algs.c:864:40-49: ERROR: reference preceded by free on line 813 drivers/crypto/hisilicon/sec/sec_algs.c:861:8-24: ERROR: reference preceded by free on line 814 drivers/crypto/hisilicon/sec/sec_algs.c:860:41-51: ERROR: reference preceded by free on line 815 drivers/crypto/hisilicon/sec/sec_algs.c:867:7-18: ERROR: reference preceded by free on line 816 It would appear than on certain error paths that we may attempt reference- after-free some memories. This patch fixes those issues. The solution doesn't look perfect, but having same memories free'd possibly from separate functions makes it tricky.
