[PATCH 5.2 032/124] bus: ti-sysc: Fix using configured sysc mask value

From: Greg Kroah-Hartman
Date: Thu Sep 19 2019 - 18:35:56 EST


From: Tony Lindgren <tony@xxxxxxxxxxx>

[ Upstream commit e212abd452a4af3174fcd469d46656f83e135a19 ]

We have cases where there are no softreset bits like with am335x lcdc.
In that case ti,sysc-mask = <0> needs to be handled properly.
