replen holds the running count of expected reply bytes.
repl will then be used by encoding routines for xdr_inline_pages offset
after which data bytes are to be received directly into the xdr
buffer pages.
NOTE: According to the nfsv4 and v4.1 RFCs, the replied tag SHOULD be the same
is the one sent, but this is not required as a MUST for the server to do so.
The server may screw us if it replies a tag of a different length in the
compound result.

Use nfs4_call_sync rather than rpc_call_sync to provide
for a nfs41 sessions-enabled interface for sessions manipulation.
The nfs41 rpc logic uses the rpc_call_prepare method to
recover and create the session, as well as selecting a free slot id
and the rpc_call_done to free the slot and update slot table
related metadata.
In the coming patches we'll add rpc prepare and done routines
for setting up the sequence op and processing the sequence result.

It has two SPI ports, typically one is connected to the application
processor and another to the baseband, this driver provides read/write
functions to its registers, irq demultiplexer and ADC
queueing/abstraction.
This chip is used on a lot of Motorola phones, it was manufactured by TI
as a custom product with the name PTWL93017, later this design evolved
into the ATLAS PMIC from Freescale (MC13783).
