Hi,

This small series contains some further cleanups to i2c-pxa:

Patch 1 gets rid of the duplication between i2c_pxa_pio_xfer() and
i2c_pxa_xfer(), which are mostly identical.

Patch 2 avoids the "exhausted retries" spamming the kernel log when
running i2cdetect - this occurs when a slave does not respond.  We
keep the existing behaviour for all other retries.

Patch 3 changes the kernel messages printed when timeouts happen so
they are unique - thus allowing identification of which one triggered.

Patch 4 removes an unnecessary show_state() while waiting for the
bus to become free.

v2: fix compile error in patch 1.
