[PATCH 09/13] syscon: Probe device first in syscon_get_regmap

[Jiaxun Yang]

When bootph-all is enabled for a syscon driver, the device
may leave unprobed when syscon_get_regmap is called by another
driver.

Perform device_probe in syscon_get_regmap, there is no side
affect as device_probe will return 0 quickly for an activated
device.
