RDMA/nes: Encapsulate logic nes_put_cqp_request()
The iw_nes driver repeats the logic
if (atomic_dec_and_test(&cqp_request->refcount)) {
if (cqp_request->dynamic) {
kfree(cqp_request);
} else {
spin_lock_irqsave(&nesdev->cqp.lock, flags);
list_add_tail(&cqp_request->list, &nesdev->cqp_avail_reqs);
spin_unlock_irqrestore(&nesdev->cqp.lock, flags);
}
}
over and over. Wrap this up in functions nes_free_cqp_request() and
nes_put_cqp_request() to simplify such code.
In addition to making the source smaller and more readable, this shrinks
the compiled code quite a bit:
