Subject: [patch v2] w1: fix for loop in w1_f29_remove_slave()
Date: Sat, 30 Jul 2011 08:19:58 +0000	[thread overview]
Message-ID: <20110730081958.GA5575@shale.localdomain> (raw)
In-Reply-To: <CAOmT4fS1OqQb5KOOeFnGHt1tnYGBRutVrAZ4cXB6n=hou5fn8w@mail.gmail.com>

The for loop was looking for i <= 0 instead of i >= 0 so this
function never did anything.  Also we started with i NB_SYSFS_BIN_FILES instead of "NB_SYSFS_BIN_FILES - 1" which is an
off by one bug.
