Subject: [PATCH] gpio: tps65912: fix wrong container_of arguments
Date: Thu, 19 Feb 2015 01:52:25 +0000 [thread overview]
Message-ID: <1424310745-28101-1-git-send-email-nicolassaenzj@gmail.com> (raw)
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.
