[ Upstream commit 02058fc3839df65ff64de2a6b1c5de8c9fd705c1 ]
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()
