From 294281373999e7fff393c04eb16092a8f00ad5aa Mon Sep 17 00:00:00 2001 From: Steve Wise Date: Fri, 11 Mar 2011 22:30:32 +0000 Subject: [PATCH] RDMA/cxgb4: Remove db_drop_task Unloading iw_cxgb4 can crash due to the unload code trying to use db_drop_task, which is uninitialized. So remove this dead code.
