From: Julia Lawall <julia@xxxxxxx> The result of container_of should not be NULL. In particular, in this case the argument to the enclosing function has passed though INIT_WORK, which dereferences it, implying that its container cannot be NULL. A simplified version of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ identifier fn,work,x,fld; type T; expression E1,E2; statement S; @@ static fn(struct work_struct *work) { ... when != work = E1 x = container_of(work,T,fld) ... when != x = E2 - if (x == NULL) S ... } // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/staging/rtl8192e/r8192E_core.c | 2 -- 1 files changed, 0 insertions(+), 2 deletions(-) diff --git a/drivers/staging/rtl8192e/r8192E_core.c b/drivers/staging/rtl8192e/r8192E_core.c index 681488b..d4fa654 100644 --- a/drivers/staging/rtl8192e/r8192E_core.c +++ b/drivers/staging/rtl8192e/r8192E_core.c @@ -1763,8 +1763,6 @@ static void rtl8192_qos_activate(struct work_struct * work) u8 u1bAIFS; u32 u4bAcParam; int i; - if (priv == NULL) - return; mutex_lock(&priv->mutex); if(priv->ieee80211->state != IEEE80211_LINKED) -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
