From mboxrd@z Thu Jan 1 00:00:00 1970 From: Guenter Roeck Date: Tue, 19 Oct 2010 16:48:19 +0000 Subject: [lm-sensors] [PATCH] lm-sensors: Fix error seen with non-sequential Message-Id: <20101019164819.GA14549@ericsson.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lm-sensors@vger.kernel.org The following patch fixes an error seen in sensors-detect if i2c bus numbering is not sequential. Problem is that in this case, $i2c_adapters[] does not exist for all index values, causing an error message whenever one of the non-existing objects is accessed. The error message is: Use of uninitialized value in string eq at ./sensors-detect line 5941.
