[ Upstream commit e526cb03e2aed42866a0919485a3d8ac130972cf ]
The last cell of 'gpio-ranges' should be number of GPIO pins, and in case of qcom platform it should match msm_pinctrl_soc_data.ngpio rather than msm_pinctrl_soc_data.ngpio - 1.
This fixes the problem that when the last GPIO pin in the range is configured with the following call sequence, it always fails with -EPROBE_DEFER.
pinctrl_gpio_set_config() pinctrl_get_device_gpio_range() pinctrl_match_gpio_range()
