Subject: crypto: api - Remove unused crypto_type lookup function
X-Git-Tag: v4.17-rc1~128^2~16
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=4989d4f07a8e738b33a79099ddbdd8e125a4da1b;p=linux.git

crypto: api - Remove unused crypto_type lookup function

The lookup function in crypto_type was only used for the implicit
IV generators which have been completely removed from the crypto
API.

This patch removes the lookup function as it is now useless.
