From 593901aa046b175e2948d361e439e13e58036146 Mon Sep 17 00:00:00 2001 From: Pramod Gurav Date: Mon, 28 Jul 2014 17:45:56 +0530 Subject: [PATCH] crypto: atmel-sha - Switch to managed version of kzalloc This patch switches data allocation from kzalloc to devm_kzalloc. It also removed some kfree() on data that was earlier allocated using devm_kzalloc(). CC: Herbert Xu CC: "David S.
