Subject: kabi: s390: struct subchannel
Patch-mainline: never, kabi
References: git-fixes

Upstream commit 05668e1d74b84c53fbe0f28565e4c9502a6b8a67 adds dma_mask
to struct subchannel. The size of this structure is not used outside of
css_alloc_subchannel(), so the new member can be added at the end without
breaking existing binary modules.
