* crypto: cavium - add release_firmware to all return caseCorentin LABBE2017-08-221-4/+9
| | | | | | | | | | | | | Two return case misses to call release_firmware() and so leak some memory. This patch create a fw_release label (and so a common error path) and use it on all return case. Detected by CoverityScan, CID#1416422 ("Resource Leak") Signed-off-by: Corentin Labbe <clabbe.montjoie@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cavium - make several functions staticColin Ian King2017-07-121-4/+4
| | | | | | | | | | The functions cvm_encrypt, cvm_decrypt, cvm_xts_setkey and cvm_enc_dec_init does not need to be in global scope, so make them static.

[-Werror=implicit-function-declaration] On the other hand, it doesn't seem to have any build dependency on ARCH_THUNDER, so let's allow compile-testing to catch this kind of problem more easily. The 64-bit dependency is needed for the use of readq/writeq.
