Subject: checkpatch: skip kernel specific checks for userspace
Date: Fri, 4 Sep 2026 13:02:30 +0200

These check are kernel specific, do not warn about it when testing
userspace code:

* BIT_MACRO
* LONG_UDELAY
* MSLEEP
* PREFER_KERNEL_TYPES
* USLEEP_RANGE

This is a follow-up to 99b70ece33d8 ("checkpatch: suppress strscpy
warnings for userspace tools").
