[PATCH] i2c: Documentation fixes
i2c documentation fixes.
>From Hideki Iwamoto:
* i2c_smbus_read_i2c_block_data is not deleted in 2.6.10. It still
exists.
* The name which can be set to i2c_driver is up to 31 characters.
>From Jean Delvare:
* Reword the paragraph about i2c_driver.name, to reflect the "new"
naming policy.
* Delete the out-of-date note about now gone inc_use and dec_use
fields.
