Subject: [PATCH 1/1] staging: hv: Convert vmbus driver interface function
pointer table to constant
From: Haiyang Zhang <haiyangz@...rosoft.com>
Convert vmbus driver interface function pointer table to constant
The vmbus interface functions are assigned to a constant - vmbus_ops.

- fix remaining checkpatch warnings and errors
