From: Mauro Carvalho Chehab <m.chehab@xxxxxxxxxxx>

commit fa1e1de6bb679f2c86da3311bbafee7eaf78f125 upstream.

The buffer size on nxt200x is not enough:

	...
	> Dec 20 10:52:04 rich kernel: [   31.747949] nxt200x: nxt200x_writebytes: i2c wr reg=002c: len=255 is too big!
	...

Increase it to 256 bytes.
