[ Upstream commit d3ca75a8b3d77f2788e6c119ea7c3e3a1ab1e1ca ]

crypto_has_skcipher() and crypto_has_skcipher2() do the same thing: they
check for the availability of an algorithm of type skcipher, blkcipher,
or ablkcipher, which also meets any non-type constraints the caller
specified.  And they have exactly the same prototype.

Therefore, eliminate the redundancy by removing crypto_has_skcipher()
and renaming crypto_has_skcipher2() to crypto_has_skcipher().

How is this a Stable-dep-of "crypto: marvell/cesa - Fix type mismatch warning"?

I don't understand why this is being backported.

You're right - it's not a dep on 5.15 but rather on 5.4, and my failed
optimization attempt did the wrong thing here. Sorry.
