From 7535b8bef067b71070ed5bdcf3606402f1e99618 Mon Sep 17 00:00:00 2001 From: Bhupesh Sharma Date: Mon, 27 Feb 2012 11:19:43 +0530 Subject: gpio/gpio-stmpe: Fix the value returned by _get_value routine The present _get_value routine returns the contents of the GPIO Monitor Pin Status Register(GPMR) starting from the bit whose value is requested to BIT 0 (irrelevant bits are replace by 0). For e.g. if we request the value of GPIO 6 in the earlier implementation the value returned is: BIT6 followed by 6 0's whereas it should just return BIT6. This patch addresses the same.
