Subject: crypto: shash - remove useless crypto_yield() in shash_ahash_digest()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=54fe792b36bb26c2cbb1557c73414e62d26d2bcc;p=openwrt%2Fstaging%2Fblogic.git

crypto: shash - remove useless crypto_yield() in shash_ahash_digest()

The crypto_yield() in shash_ahash_digest() occurs after the entire
digest operation already happened, so there's no real point.  Remove it.
