From: Alexander Stein <alexanders83@xxxxxx>

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

===============

commit d25221525e0e2cfd70e4ec7216549c06609a8bd2 upstream.

Adjust the bulk message timeout to the other ones (1000ms). Otherwise the
following dmesg errors can be seen on a Raspberry Pi:
[   31.492386] Failed to read 1-wire data from 0x81: err=-110.
[   31.504168] 0x81: count=-110, status:
[   31.613404] Failed to read 1-wire data from 0x81: err=-110.
[   31.621915] 0x81: count=-110, status:
[   43.260968] Failed to read 1-wire data from 0x81: err=-110.
[   43.270998] 0x81: count=-110, status:
