Rework for_each_requested_gpio_in_range() to use the new helper to retrieve a dynamically allocated copy of the descriptor label and free it at the end of each iteration. We need to leverage the CLASS()' destructor to make sure that the label is freed even when breaking out of the loop. Signed-off-by:

gpiochip_is_requested() not only has a misleading name but it returns a pointer to a string that is freed when the descriptor is released. Provide a new helper meant to replace it, which returns a copy of the label string instead. Signed-off-by:

The pinconf-groups debugfs file dumps each valid configuration item of all pin groups. Some platforms and devices may have pin groups which cannot be accessed, according to commit 691bf5d5 ("pinctrl: qcom: Don't allow protected pins to be requested"). Fail for each configuration item of an invalid pin group by checking the GPIO chip's valid mask. The validity of the pin group cannot be checked in the generic pinconf dump (function "pinconf_generic_dump_one"), as it does not directly interact with the gpiochip or the pinmux callbacks (which would give it access to the request callback). Instead, an entry contains the ID and name of the pingroup with no properties when all items fail. Signed-off-by:

of_property_count_u32_elems() might return an error code in some cases. It's naturally better to assign what it's returned to the err variable and supply the real code to the upper layer(s). Besides that, it's a common practice to avoid assignments for the data in cases when we know that the error condition happened. Refactor the code accordingly. Signed-off-by:
