4.2.8-ckt1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Bart Van Assche <bart.vanassche@xxxxxxxxxxx>
commit db7489e07669073970358b6cacf6a9dd8dc9275e upstream.
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")
