Subject: bus: ti-sysc: Fix using configured sysc mask value
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e212abd452a4af3174fcd469d46656f83e135a19;p=linux.git

bus: ti-sysc: Fix using configured sysc mask value

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.
