Subject[PATCH 4.18 180/228] bus: ti-sysc: Fix no_console_suspend handling
Date
4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tony Lindgren <tony@atomide.com>

[ Upstream commit 4f3530f4a41d49c41015020cd9a5ed5c95b5d2db ]

If no_console_suspend is set, we should keep console enabled during suspend.
Lets fix this by only producing a warning if we can't idle hardware during
suspend.

Fixes: ef55f8215a78 ("bus: ti-sysc: Improve suspend and resume handling")
