ALSA driver calls Media Controller start/stop pipeline
interfaces from IRQ handler. Start/stop pipeline lock
graph_mutex which is unsafe from a IRQ handler. Convert
graph_mutex into a spinlock and call it graph_lock. IRQ
safe start/stop pipeline interfaces will be added based
on this change.

That seems weird, are you saying you can't use
obd_device_list_sops and obd_device_list_fops are not referenced
outside of linux-module.c, and in the general use case
struct file_operations and struct seq_operations should be a const
object, so make them static and const.
This patch fixes the following sparse warnings:

Linux kernel has supported VME bus since 2009. The support comes in a form
of kernel driver API that is backed by a couple drivers for PCI-VME
bridges. There is also a vme_user driver that provides a generic userpsace
