From 7f4e985448e82fe4a1cc0ae4fcecaf7e0301c07b Mon Sep 17 00:00:00 2001 From: Vikram Pandita Date: Mon, 9 Nov 2009 21:24:32 -0600 Subject: [PATCH] usbtest: make module param pattern writeable Allow module_param to be writeable. This allows us to change the parameter if usbtest is built-in in the kernel.
