From bafeafeab94b8d3019aac15c2df2ce47b08a6363 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Fri, 13 Jan 2012 09:32:16 +1030 Subject: module_param: check type correctness for module_param_array module_param_array(), unlike its non-array cousins, didn't check the type of the variable. Fixing this found two bugs.
