Subject: [PATCH 01/13] powerpc/powernv: remove get_cxl_module
Date: Thu, 28 Jan 2021 19:14:09 +0100
Message-ID: <20210128181421.2279-2-hch@lst.de> (raw)
In-Reply-To: <20210128181421.2279-1-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.
