[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 * Delete the out-of-date note about now gone inc_use and dec_use fields.
