Subject: [PATCH] ath6kl: Use cc-disable-warning to disable -Wdangling-pointer

Git-commit: 48a75b979940f8aa838143e976455aa0e629e638

Patch-mainline: v5.19-rc1

References: bsc#1206451

Clang does not support this option so the build fails:

  error: unknown warning option '-Wno-dangling-pointer' [-Werror,-Wunknown-warning-option]

Use cc-disable-warning so that the option is only added when it is

supported.

Fixes: bd1d129daa3e ("wifi: ath6k: silence false positive -Wno-dangling-pointer warning on GCC 12")
