Documentation/process/coding-style.rst chapter 4 "Naming" says:
"""
For symbol names and documentation, avoid introducing new usage of
'master / slave' (or 'slave' independent of 'master') and 'blacklist /
whitelist'.
Recommended replacements for 'master / slave' are:
'{primary,main} / {secondary,replica,subordinate}'
'{initiator,requester} / {target,responder}'
'{controller,host} / {device,worker,proxy}'
'leader / follower'
'director / performer'
Recommended replacements for 'blacklist/whitelist' are:
'denylist / allowlist'
'blocklist / passlist'
"""
So I've done a s/whitelist/allow/ on your patch.

There is a bunch of extra spaces here which go against the codingstyle, I've fixed this up
while applying this to my tree:
Thank you for your patch, I've applied this patch to my review-hans
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans
