From efdf83c1763156220a74c8f2755c1a6fa1e1c26b Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Fri, 20 Nov 2009 11:32:38 +0000 Subject: [PATCH] Staging: comedi: pcl816: update convert_src mask for AI cmdtest The COMEDI_CMDTEST ioctl needs to clear unsupported bits in the struct comedi_cmd's convert_src and other *_src members. This needs fixing in the pcl816 driver's AI cmdtest.
