From 585985429080a449e0ecf66dd485899a8765c26c Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 17 Apr 2011 16:51:36 -0700 Subject: [PATCH] bna: Fix set-but-unused variables. The variable 'pgoff' is set but unused in bfa_nw_ioc_fwver_get() and bfa_ioc_download_fw(). Similarly for 'cmd_h' in bna_mbox_flush_q and the entirety of bna_rit_mod_uninit() is unused since variables are purely set but no action is made using them. Same for 'bna' in bna_rit_create() and 'ret' in bna_rx_create(). Just kill them off. Signed-off-by: David S.
