Date: Tue, 11 Sep 2012 15:58:14 -0700 From: "Ira W. Snyder" <iws@...o.caltech.edu> To: linux-kernel@...r.kernel.org Cc: linux-can@...r.kernel.org, sameo@...ux.intel.com, "Ira W. Snyder" <iws@...o.caltech.edu> Subject: [PATCH 1/2] mfd/janz-cmodio: fix MODULBus number sysfs entry From: "Ira W. Snyder" <iws@...o.caltech.edu> Revision 1.0 of the Janz CMOD-IO Carrier Board does not contain zeroes in the top 4 bits of the modulbus_num (int_enable) register. Mask off the unused bits so that the correct value is displayed in sysfs. Cc: Samuel Ortiz <sameo@...ux.intel.com> Signed-off-by: Ira W.
