[PATCH 1/3] staging: vchiq_arm: add reference to vchiq device in vchiq_state

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a reference to the vchiq device in the vchiq_state structure. This
allows the device structure to be passed around, which will be useful in
order to get rid of the global g_dev structure.
