Subject: [PATCH] ima: Fix potential memory leak in ima_init_crypto()
[ Upstream commit 067d2521874135267e681c19d42761c601d503d6 ]
On failure to allocate the SHA1 tfm, IMA fails to initialize and exits
without freeing the ima_algo_array. Add the missing kfree() for
ima_algo_array to avoid the potential memory leak.
