The kpc2000 driver does not verify whether or not mapping the I/O
space succeeded during probe time. Make the driver verify that the
mapping operation was successful before potentially using that area
in the future.

The kpc_i2c driver attempts to map its I/O space without verifying
whether or not the result of platform_get_resource() is NULL. Make the
driver check that platform_get_resource did not return NULL before
attempting to use the value returned to map an I/O space.

The i2c_device structure contains a member used to stash a pointer to
a platform_device. The driver contains no cases of this member being
used after initialization. Remove the unnecessary struct member and
the initialization of this member in the sole instance where the

The kpc2000_i2c.c file contains instances of unnecessary consecutive
newlines which impact the readability of the file. Remove these
unnecessary newlines.

In pi2c_probe, a rw_sem is initialized and stashed off in the
i2c_device private runtime state struct. This rw_sem is never used
after initialization. Remove the rw_sem and cleanup unneeded header
inclusion.

The kpc_i2c driver does not unmap its I/O space upon error cases in the
probe() function or upon remove(). Make the driver clean up after itself
more maintainably by using the managed resource API.

The kpc_i2c driver stashes private state data in the platform_data
member of its device structure. In general, the platform_data structure
is used for passing data to the driver during probe() rather than as a
storage area for runtime state data. Instead, use the drvdata member
for all state info m
The FEATURES_* symbols use bit shifting of the style (1 << k) in order
to assign a certain meaning to the value of inividual bits being set
in the value of a given variable. Instead, use the BIT() macro in
order to improve readability and maintain consistency with the rest
of the kernel.

This series contains some patches aimed toward:
- cleaning up unused/unneeded parts of driver state
- a couple of small style fixups
- a couple of API changes
- better error handling in probe()
in the kpc2000 i2c driver.

Hi Paul,
Besides the missing SoB I have two more comments:
