If anyone has any objections, please let me know. ------------------ From: Nicolas Saenz Julienne commit 2f97c20e5f7c3582c7310f65a04465bfb0fd0e85 upstream. The gpio_chip operations receive a pointer the gpio_chip struct which is contained in the driver's private struct, yet the container_of call in those functions point to the mfd struct defined in include/linux/mfd/tps65912.h.
