Subject: [PATCH] MMC/SD: Fix regression in 2.6.23-git3 due to change in
 calling add_uevent_var

In commit 7eff2e7a8b65c25920207324e56611150eb1cd9a, the calling sequence
for add_uevent_var was changed, but the ssb driver was not modified, which
leads to a "Unable to handle kernel paging request" oops. This patch fixes
the problem.
