From be2cfac07619a8f97fe3aae39f095e9e33decd99 Mon Sep 17 00:00:00 2001 From: Tadeusz Struk Date: Tue, 22 Sep 2015 11:57:47 -0700 Subject: [PATCH] crypto: qat - remove empty functions and turn qat_uregister fn to void Some code cleanups after crypto API changes: - Change qat_algs_unregister to a void function to keep it consistent with qat_asym_algs_unregister. - Remove empty functions qat_algs_init & qat_algs_exit.
