^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You should probably use scripts/checkpatch.pl on your proposed
patches
before sending them.

You've got a lot of tabs and spaces after every line continuation.
Please coalesce the format on a single line and avoid this defect.

pr_err("impossible to appraise a module without a file descriptor. sig_enforce kernel parameter might help\n");
