i2c-powermac: Drop temporary name buffer
We no longer need to write the adapter name to a temporary buffer. We can write it directly to the i2c_adapter's name field. This is more efficient. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Michel Daenzer <michel@daenzer.net> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org>
