[PATCH] Fix the epca driver to permit epca_setup() to be invoked fromthe kernel cmdline

From: David Howells
Date: Wed Jul 09 2008 - 09:20:29 EST


Fix the epca driver to call epca_setup() if digiepca=xxx is included on the
command line and the epca driver is built in.

epca_setup() used to be called from init/main.c in 2.2 kernels, but somewhere
along the way that call was removed but not replaced.
