[PATCH 0/2] serdev API extension

[Andrey Smirnov <andrew.smirnov@gmail.com>]

Rob,

These patches are a continuation of discussion about adding
functionality to serdev API we had off-list.

Being added are a function to do a blocking write capable of
dispatching multiple calls to write_buf() and some very minimalistic
bus locking API.

Any feedback is appreciated.

Thanks,
Andrey Smirnov
