From 87e51b072485f519c6ef077f60f4b837677202cc Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 18 Jun 2015 14:25:55 +0800 Subject: [PATCH] crypto: caam - Reintroduce DESC_MAX_USED_BYTES I incorrectly removed DESC_MAX_USED_BYTES when enlarging the size of the shared descriptor buffers, thus making it four times larger than what is necessary. This patch restores the division by four calculation.
