[PATCH] crypto: inside-secure - select CONFIG_CRYPTO_SM3

[PATCH] crypto: inside-secure - select CONFIG_CRYPTO_SM3

[Arnd Bergmann]

Without this symbol, the safexcel driver causes a link error:

drivers/crypto/inside-secure/safexcel_hash.o: In function `safexcel_ahash_final':
safexcel_hash.c:(.text+0x3c4): undefined reference to `sm3_zero_message_hash'

Fixes: 0f2bc13181ce ("crypto: inside-secure - Added support for basic SM3 ahash")

Was this problem observed with the latest state of the Cryptodev GIT?
Because I already attempted to fix this issue with commit 99a59da3723b9725
Can you please double check if you still get the compile error with that
commit included?
(I can't tell from this mail which version of the sources you are using)

I was testing on linux-5.4-rc3 plus some of my own patches, so your fix
was not included.

With your patch applied, mine is no longer needed.
