I think it is.

# git grep GENERIC_HARDIRQS_NO_DEPRECATED arch/
arch/sh/Kconfig:        select GENERIC_HARDIRQS_NO_DEPRECATED

Though the question remains, whether this driver is actually used with
sh platforms. If yes, then pushing the already existing change to
Linus is the right way to go. If no, adding a "depends on !SH" is the
simple fix to prevent this allmodconfig fallout. Another option is to
ignore it :) I leave that up to Paul.

Right that changelog sucks. :)
