From: "Ira W. Snyder" <redacted> 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 <redacted> Signed-off-by: Ira W. Snyder <redacted>
Who will take care of this patch? Marc
