From 54e4a0c486041dc1c20593d997fafd67089e8408 Mon Sep 17 00:00:00 2001 From: Faiz Abbas Date: Tue, 3 Jul 2018 16:47:10 +0530 Subject: [PATCH] can: m_can: Move accessing of message ram to after clocks are enabled MCAN message ram should only be accessed once clocks are enabled. Therefore, move the call to parse/init the message ram to after clocks are enabled.
