4.18-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 833eacc7b5913da9896bacd30db7d490aa777868 ]
The MXS driver was calling back into the GPIO API from its irqchip. This is not very elegant, as we are a driver, let's just shortcut back into the gpio_chip .get() function instead.
This is a tricky case since the .get() callback is not in this file, instead assigned by bgpio_init(). Calling the function direcly in the gpio_chip is however the lesser evil.
