From 3a0944c5362654e13cde558ef81309a0fcf9112b Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Tue, 20 Aug 2019 13:23:54 -0700 Subject: crypto: caam - share definition for MAX_SDLEN MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Both qi.h and cammalg_qi2.h seem to define identical versions of MAX_SDLEN. Move it to desc_constr.h to avoid duplication.
