Use kzalloc rather than kmalloc followed by memset with 0
drivers/net/ethernet/qlogic/qed/qed_dcbx.c:1280:13-20: WARNING:
kzalloc should be used for dcbx_info, instead of kmalloc/memset
Generated by: scripts/coccinelle/api/alloc/kzalloc-simple.cocci
Originally was fixed in:
'commit 561ed23331df ("qed: fix kzalloc-simple.cocci warnings")'
But later warning was introduced in:
'commit 62289ba27558 ("qed: Fix possible system hang in the
dcbnl-getdcbx() path.")'
