If CRYPTO_DEV_SAFEXCEL is y but CRYPTO_SM3 is m,
building fails:
drivers/crypto/inside-secure/safexcel_hash.o: In function `safexcel_ahash_final':
safexcel_hash.c:(.text+0xbc0): undefined reference to `sm3_zero_message_hash'
Select CRYPTO_SM3 to fix this.

I don't really want to build SM3 into the kernel for all Inside Secure drivers, since in the majority of cases, the HW will not actually support SM3 and I don't want to bloat the kernel image in that case. So maybe it's better to #ifdef out the failing part of the driver if CONFIG_SM3 is not set?

If that is really the case - don't have time to look into that right now - then I would be fine with that too. If no one objects, then I will make a patch for that when I can find some time to do so (~early next week).

I'm not sure what happens there is the module is configured to be a loadable module though. 2)I cannot reproduce the build error when I set CONFIG_CRYPTO_SM3 to "m". But I think I'll just spin a patch that *always* takes the local version independent of the CONFIG switch. That should always work.
