From e3ed2bdfc4a5dcdcdf74141e88af9990dc141a4b Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 2 Jul 2012 23:03:02 +0100 Subject: [PATCH] sfc: Use dev_kfree_skb() in efx_end_loopback() Fix CID 102619 in the Coverity report on Linux. efx_end_loopback() iterates over an array of skb pointers of which some may be null (if efx_begin_loopback() failed). It should not use dev_kfree_skb_irq(), which requires non-null pointers. In practice this is safe because it does not run in interrupt context and therefore always ends up calling dev_kfree_skb(), which does allow null pointers. But we should make that explicit.
