[PATCH 4.9 019/104] reset: ti_syscon: fix a ti_syscon_reset_status issue

[Greg Kroah-Hartman]

4.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Jiancheng Xue <xuejiancheng@xxxxxxxxxxxxx>


[ Upstream commit 5987b4bf512101137fa60c5c0ccac3db51541221 ]

If STATUS_SET was not set, ti_syscon_reset_status would always return 0
no matter whether the status_bit was set or not.
