Subject[PATCH v2 08/13] net: lpc-enet: fix badzero.cocci warnings
Date
From: kbuild test robot <lkp@intel.com>

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.

Generated by: scripts/coccinelle/null/badzero.cocci

Fixes: e42016eb3844 ("net: lpc-enet: allow compile testing")
