Subject: [Resending PATCH 1/4] W1: export w1_read_8 function

From: Madhusudhan Chikkature <madhu.cr@...com>

This patch exports the w1_read_8 function for use of drivers.
The OMAP HDQ driver(drivers/w1/masters/omap_hdq.c) uses this function.

Signed-off-by: Madhusudhan Chikkature<madhu.cr@...com>
Acked-by: Evgeniy Polyakov <johnpol@....mipt.ru>
---
The OMAP HDQ add device patch is dropped from the series
as it has already gone upstream through the linux omap tree
