[PATCH 0/9] Fix Marvell mv63xxx I2C driver

[Russell King - ARM Linux]

This patch series fixes a whole chunk of problems with this driver,
discovered with the Marvell Armada 510 chip on the Solid-run cubox.

Most notable of these is the I2C driver aborting a transaction
because a signal is pending - which might be SIGPIPE or SIGALRM
for the process.  Meanwhile, the calling driver may be in the
middle of a critical read-modify-write cycle on a device register,
causing it to fail.

Other problems are race conditions in the handling of multi-part
messages, where we end up sending multiple start conditions -
sometimes more times than we have i2c_msg's to send.

Lastly is the rather poor probe error handling, which ranges from
non-existent to lacking propagating the provided error code.
