[PATCH 1/1] W1: ds2490: Increase timeout when waiting for status

[Alexander Stein]

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:
