Subject: blk-crypto: remove blk_crypto_insert_cloned_request()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=435c0e999689b7f383d0a27978cdaa08669cf134;p=linux.git

blk-crypto: remove blk_crypto_insert_cloned_request()

blk_crypto_insert_cloned_request() is the same as
blk_crypto_rq_get_keyslot(), so just use that directly.
