[PATCH] bus: ti-sysc: Do not disable on suspend for no-idle

From: Tony Lindgren
Date: Thu Jul 02 2020 - 16:58:37 EST


If we have "ti,no-idle" specified for a module we must not disable
the the module on suspend to keep things backwards compatible.

Fixes: 386cb76681ca ("bus: ti-sysc: Handle missed no-idle property in addition to no-idle-on-init")
