Subject: [PATCH 01/13] powerpc/powernv: remove get_cxl_module
Date:   Tue,  2 Feb 2021 13:13:22 +0100
Message-Id: <20210202121334.1361503-2-hch@lst.de>

The static inline get_cxl_module function is entirely unused since commit
8bf6b91a5125a ("Revert "powerpc/powernv: Add support for the cxl kernel
api on the real phb"), so remove it.
