Subject: [PATCH] regulator: fan53555: suppress warning about uninitialized variable
X-SA-Exim-Version: 4.2.1 (built Wed, 08 May 2019 21:11:16 +0000)
X-SA-Exim-Scanned: Yes (on metis.whiteo.stw.pengutronix.de)
In function 'fan53555_device_setup', a call to 'regmap_update_bits' is
made with the mode_mask variable potentially uninitialized.
This can be the case if di->vendor is FAN53526_VENDOR_FAIRCHILD and
di->sleep_vsel_id is not handled by the case (neither FAN53555_VSEL_ID_0 nor FAN53555_VSEL_ID_1).
I am not sure how likely it is to happen.
