Subject: [ 39/95] S390: qdio: fix handler function arguments for zfcp data router

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Steffen Maier <maier@...ux.vnet.ibm.com>

commit 7b3cc67d4445995a025a4b55a7dc687b6829b4ca upstream.

Git commit 25f269f17316549e "[S390] qdio: EQBS retry after CCQ 96"
introduced a regression in regard to the zfcp data router.
Revoke the incorrect simplification of the function call arguments
for the qdio handler to make the zfcp hardware data router working
again.

This is applicable to 3.2+ kernels.
