The free_device_compression_mode(iaa_device, device_mode) function frees "device_mode" but it iss passed to iaa_compression_modes[i]->free() a few lines later resulting in a use after free. The good news is that, so far as I can tell, nothing implements the ->free() function and the use after free happens in dead code. But, with this fix, when something does implement it, we'll be ready. :) Fixes: b190447e ("crypto: iaa - Add compression mode management along with fixed mode") Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org> Reviewed-by: Tom Zanussi <tom.zanussi@linux.intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
