ima_init_crypto() allocates a memory chunk for "ima_algo_array" with kcalloc(). When some errors occur, the function jumps to "out_array" and releases the "ima_algo_array[i].tfm". But "ima_algo_array" is not released, which will lead to a memory leak. We can release the ima_algo_array with kfree() when some errors occur to fix the memory leak.
