Subject: crypto: api - Fold crypto_alloc_tfmmem() into crypto_create_tfm_node()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0200de9d75b15babaa608819b797400198b5b4fc;p=thirdparty%2Flinux.git

crypto: api - Fold crypto_alloc_tfmmem() into crypto_create_tfm_node()

Fold crypto_alloc_tfmmem() into its only remaining caller,
crypto_create_tfm_node().  Previously crypto_alloc_tfmmem() was called
by crypto_clone_tfm(), but crypto_clone_tfm() was removed.

This rolls back the refactoring that was done in commit 3c3a24cb0ae4
("crypto: api - Add crypto_clone_tfm").
