From: Greg Kroah-Hartman
Date: Tue Feb 11 2014 - 15:51:55 EST


3.13-stable review patch. If anyone has any objections, please let me know.

------------------

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.
