[PATCH 5.15 127/137] gpio: vf610: set value before the direction to avoid a glitch

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

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

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

From: Haibo Chen <haibo.chen@xxxxxxx>

commit fc363413ef8ea842ae7a99e3caf5465dafdd3a49 upstream.

We found a glitch when configuring the pad as output high. To avoid this
glitch, move the data value setting before direction config in the
function vf610_gpio_direction_output().

Fixes: 659d8a62311f ("gpio: vf610: add imx7ulp support")
