v9->v10:
	* fixed style issues that were checked out by checkpatch.pl.
	* In Patch 3 in wmt_i2c_write() function, deleted the log
	  when received nack.
	* In Patch 4 in viai2c_irq_xfer() function, return 1 for
	  I2C_SMBUS_QUICK access.
	* In Patch 6 in zxi2c_get_bus_speed() function, adjusted
	  the log when firmware gives inappropriate parameters.

v8->v9:
	* In Patch 1 in probe() do not return at the
	  i2c_add_adapter(), but call clk_disable_unprepare()
	  in case of failure.
	* In Patch 2 fix the conflict when i2c-wmt.c is removed.
	* In Patch 2 in wmt_i2c_probe() function, call
	  clk_disable_unprepare() in case of failure. While at
	  it, add a comment to explain the reason.
	* When renaming i2c_dev to i2c, change also the reference
	  in clk_disable_unprepare().
