Please run scripts/checkpatch.pl and fix reported warnings. Then please
run `scripts/checkpatch.pl --strict` and (probably) fix more warnings.
Some warnings can be ignored, especially from --strict run, but the code
here looks like it needs a fix. Feel free to get in touch if the warning
is not clear.

You did not even run basic tools... I doubt that this was ever built
with W=1 and static checkers.

But above warning about undocumented ABI is a NAK.

Please run standard kernel tools for static analysis, like coccinelle,
smatch and sparse, and fix reported warnings. Also please check for
warnings when building with W=1. Most of these commands (checks or W=1
build) can build specific targets, like some directory, to narrow the
scope to only your code. The code here looks like it needs a fix. Feel
free to get in touch if the warning is not clear.
