IB/core, cma: Make __attribute_const__ declarations sparse-friendly
Move the __attribute_const__ declarations such that sparse understands that these apply to the function itself and not to the return type. This avoids that sparse reports error messages like the following: drivers/infiniband/core/verbs.c:73:12: error: symbol 'ib_event_msg' redeclared with different type (originally declared at include/rdma/ib_verbs.h:470) - different modifiers Fixes: 2b1b5b601230 ("IB/core, cma: Nice log-friendly string helpers") Signed-off-by: Bart Van Assche <bart.vanassche@sandisk.com> Cc: Sagi Grimberg <sagig@mellanox.com> Reviewed-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
