A new warning in Clang 22 [1] complains that @clidr passed to get_clidr_el1() is an uninitialized const pointer. get_clidr_el1() doesn't really care since it casts away the const-ness anyways.
Silence the warning by initializing the struct.
This patch won't apply to anything past v6.1 as this code section was reworked in Commit 7af0c2534f4c ("KVM: arm64: Normalize cache configuration"). There is no upstream equivalent so this patch only needs to be applied (stable only) to 6.1.

Resending this with Nathan's RB tag, an updated commit log and better recipients from checkpatch.pl.
My usage of $ b4 trailers must've not been correct because this 6.1 version didn't pick up Nathan's RB tag. Whoops! Hopefully whoever picks this up can add that for me :)
Looks like you resent the first iteration of this change [1] instead of the second [2], hence why 'b4 trailers -u' did not work, since I never reviewed the first iteration after Marc rejected it :)
Your 5.15 resend looks correct though.
