And based on another patch I was looking at checkpatch agrees :)

It also suggests as a check that this could be written !adapter rather than NULL == adapter

CHECK: Comparison to NULL could be written "!adapter"
#27: FILE: drivers/net/ethernet/intel/igb/igb_main.c:8276:
+	if (adapter == NULL) {

total: 0 errors, 0 warnings, 1 checks, 16 lines checked

Your patch has style problems, please review.

NOTE: If any of the errors are false positives, please report
      them to the maintainer, see CHECKPATCH in MAINTAINERS.
