commit 50c697215a8cc22f0e58c88f06f2716c05a26e85 upstream.

Hi Greg,

Please yank this commit from all the stable queues -- it needs Some further baking, and a revert is queued in Andrew's tree.

Thanks, sam

Add missing <linux/string.h> include for strcmp.

Clang 16 makes -Wimplicit-function-declaration an error by default. Unfortunately, out of tree modules may use this in configure scripts, which means failure might cause silent miscompilation or misconfiguration.
