Subject: [PATCH] Support Linux 6.4

With Linux 6.4 commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1aaba11da9aa7d7d6b52a74d45b31cac118295a1
class_create() doesn't require first argument THIS_MODULE anymore so let's
drop first argument if Linux version >= 6.4

Upstream: https://github.com/embeddedTS/wilc3000-external-module/pull/5
