From f76ebe2d75bee65709fd41ea3fd763a57f85cdec Mon Sep 17 00:00:00 2001 From: Tzafrir Cohen Date: Tue, 17 Jan 2012 14:26:25 +0000 Subject: [PATCH] Build OSLEC EC if in the tree Build the OSLEC echo canceller (drivers/staging/echo and dahdi_echocan_oslec) if the code of oslec is present in the tree. Also closing another issue regarding documentation of building OSLEC, as it is now even clearer than before. Patch has been used in the Debian package for quite some time.
