From 6cfa694f0fa7bb428e2a93ff9fb0bc4c1370d343 Mon Sep 17 00:00:00 2001 From: Ajay Singh Date: Mon, 23 Apr 2018 22:03:04 +0530 Subject: [PATCH] staging: wilc1000: removed unused static variables for gtk and ptk information Removed the unnecessary static variables used to store gtk and ptk information. Key data stored in the params was never access using these variables. Variables given below are removed g_add_gtk_key_params; g_key_gtk_params; g_add_ptk_key_params; g_key_ptk_params; g_key_wep_params; g_ptk_keys_saved; g_gtk_keys_saved; g_wep_keys_saved; Signed-off-by: Ajay Singh Reviewed-by: Claudiu Beznea Reviewed-by: Dan Carpenter Signed-off-by: Greg Kroah-Hartman --- drivers/staging/wilc1000/wilc_wfi_cfgoperations.c | 80 ----------------------- 1 file changed, 80 deletions(-) diff --git a/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c b/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c index f9a95f2..402f12e 100644 --- a/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c +++ b/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c @@ -166,15 +166,6 @@ struct add_key_params { u8 *mac_addr;
