How about this:

The function pointer has
sure the CapsLock state of the VM's

fix this later, probably by tracking the state of virtual CapsLock, because
it looks the keyboard module doesn't supply an API for us to query the state

I got the hypercall error code on Hyper-V 2008 R2 when keeping running
rmmod hv_netvsc; modprobe hv_netvsc; rmmod hv_utils; modprobe hv_utils
in a Linux guest.
Without the patch, the driver can occasionally fail to load.

Without this patch, the state is put to CHANNEL_OPENING_STATE, and when
the driver is loaded next time, vmbus_open() will fail immediately due to
newchannel-state != CHANNEL_OPEN_STATE.

Before the line vmbus_open() returns, srv-util_cb can be already running
and the variablies, like util_fw_version, are needed by the srv-util_cb.
So we have to make sure the variables are initialized before the vmbus_open().

, the driver can occasionally fail to load.
Also let's retry HV_STATUS_INSUFFICIENT_MEMORY, though we didn't get it
before.
Removed 'case -ENOMEM', since the hypervisor doesn't return this.

v2: I removed the FCP prefix as Greg asked.
I also updated the output message a little:
FCP: failed to acquire the semaphore --
can not acquire the semaphore: it is benign
