From 772775c1dfe00c99a9fe449ed35f74f1067f0128 Mon Sep 17 00:00:00 2001 From: kbuild test robot Date: Fri, 9 Aug 2019 16:40:34 +0200 Subject: [PATCH] net: lpc-enet: fix badzero.cocci warnings drivers/net/ethernet/nxp/lpc_eth.c:1316:31-32: WARNING comparing pointer to 0 Compare pointer-typed values to NULL rather than 0 Semantic patch information: This makes an effort to choose between !x and x == NULL. !x is used if it has previously been used with the function used to initialize x. This relies on type information. More type information can be obtained using the option -all_includes and the option -I to specify an include path.
