Subject: gpio: Fix null pointer dereference while accessing rdc321x
platform_data
From: Florian Fainelli <[email protected]>
commit fa6469cb5b2d16703464c344b943e2c025cb7858 upstream.
rdc321x-gpio currently fetches its driver specific data by using the
platform_device->platform_data pointer, this is wrong because the mfd
device which registers our platform_device has been added using
mfd_add_device() which sets the platform_device->driver_data pointer
instead.
