Subject[PATCH 3/3] gpio: brcmstb: remove custom 'brcmstb_gpio_set_names'
Date
Gpiolib core code has been updated to support setting
friendly names through properly 'gpio-line-names'.
Instead of redefine behaviour here to skip the core
to be executed, just properly assign the desired offset
per bank to get in the core the expected behaviour.
