Subject: [PATCH] Documentation: gpio: fix function links in the HTML docs

The shorthand [_data] and [devm_] cause the HTML documentation to not
link to the function documentation properly. This expands the references
to the complete function names with the exception of
devm_gpiochip_remove() which was dropped by commit 48207d7595d2 ("gpio:
drop devm_gpiochip_remove()").

Often a gpio_chip is part of an instance-specific structure with states not
exposed by the GPIO interfaces, such as addressing, power management, and more.

This does not apply to v5.3-rc1 can you rebase and resend?

Thanks!
