Subject: [PATCH] crypto: dh - Remove pointless checks for NULL 'p' and 'g'
Git-commit: ced6a58638432c9f731184f908208d539725ba82
References: FATE#326323
Patch-mainline: v4.15
Neither 'p' nor 'g' can be NULL, as they were unpacked using
crypto_dh_decode_key(). And it makes no sense for them to be optional.
So remove the NULL checks that were copy-and-pasted into both modules.
