Subject: [PATCH] gpio: drop broken to_gpio_irq_chip() helper

mainline inclusion
from mainline-5.0-rc1
commit eee3919c5f2949a8b7b1e9fa239d153be1538656
category: bugfix
bugzilla: 5548
CVE: NA

---------------------------

Drop the broken to_gpio_irq_chip() container_of() helper, which would
break the build for anyone who tries to use it.

Specifically, struct gpio_irq_chip only holds a pointer to a struct
irq_chip so using container_of() on an irq-chip pointer makes no sense.
