    Subject[PATCH 5.10 147/154] RDMA/netlink: Add __maybe_unused to static inline in C file
    Date
    From: Leon Romanovsky <leonro@nvidia.com>

    commit 83dde7498fefeb920b1def317421262317d178e5 upstream.

    Like other commits in the tree add __maybe_unused to a static inline in a
    C file because some clang compilers will complain about unused code:

    >> drivers/infiniband/core/nldev.c:2543:1: warning: unused function '__chk_RDMA_NL_NLDEV'
    MODULE_ALIAS_RDMA_NETLINK(RDMA_NL_NLDEV, 5);
    ^

    Fixes: e3bf14bdc17a ("rdma: Autoload netlink client modules")
