From 52911e03565c896be5a5bdb155df2d512e1b9f3e Mon Sep 17 00:00:00 2001 From: Rex Zhu Date: Wed, 7 Mar 2018 13:49:03 +0800 Subject: [PATCH] drm/amd/pp: Remove meanless return value check in RV In send_message_to_smu helper functions, Print out the error code for debug if smu failed to response. The helper functions always return true, so no need to check their return value.
