NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

NOTE: Whitespace errors detected.
      You may wish to use scripts/cleanpatch or scripts/cleanfile

Commit 9b4d7d8fd95d ("bpf: Separate bpf_throw() and bpf_exit() return value validation") has style problems, please review.
