I encountered bug in SX1502 expander driver in 5.7.7. Here is relevant
DTS part:

compatible = "semtech,sx1502q";
gpio4_cfg_pins: gpio2-cfg {
                         pins = "gpio5";
                         output-high;
     };

And part of OOPS:

[    0.673996] [<c023cfa6>] (gpiochip_get_data) from [<c023b235>]
(sx150x_gpio_direction_output+0xd)
[    0.683259] [<c023b235>] (sx150x_gpio_direction_output) from
[<c023b363>] (sx150x_pinconf_set+0x)
[    0.692796] [<c023b363>] (sx150x_pinconf_set) from [<c0238fef>]
(pinconf_apply_setting+0x39/0x7e)
[    0.701635] [<c0238fef>] (pinconf_apply_setting) from [<c0236c77>]
(pinctrl_commit_state+0xa5/0x)
[    0.710648] [<c0236c77>] (pinctrl_commit_state) from [<c0237e03>]
(pinctrl_enable+0xff/0x1d4)
[    0.719139] [<c0237e03>] (pinctrl_enable) from [<c023b791>]
(sx150x_probe+0x1a3/0x358)
[    0.727027] [<c023b791>] (sx150x_probe) from [<c02c38bf>]
(i2c_device_probe+0x1bb/0x1dc)

The problem is that sx150x_pinconf_set uses sx150x_gpio_direction_output
but gpio is not setup yet. Patch below fixes it but I'm not sure whether
is it correct.
