Thank you so much for your review.
Yes, I agree but I see that this keeps growing.
In 5.15 kernel there were 10 warnings:
total: 0 errors, 10 warnings, 2010 lines checked

But now in the 6.12 kernel it becomes 20.
total: 1 errors, 20 warnings, 2253 lines checked

This means new warnings were introduced while the old ones still remain.
Thus I thought it's better to reduce it.

Oh yes, thanks for pointing this out.
Unfortunately checkpatch does not report this.
But I tried adding braces and no issues either.
I will push the new patchset with this change.

Thanks,
