Use i2c_10bit_addr_*_from_msg() helpers instead of local copy. No functional change intended. Signed-off-by: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
Can we please do the helper conversion as one commit and the (much needed) cleanup of assigning len and de-duplicating the call to mtk_i2c_cmd() as two commits? One with just the conversion, one with the cleanup (or in inverse order, as you wish). Thanks, Angelo
