Emil's patch, would that be:

    wlcore: Fix regression in wlcore_set_partition()

    The commit 3719c17e1816 ("wlcore/wl18xx: fw logger over sdio")
    introduced a
        regression causing the wlcore to time out and go into
    recovery. Reverting the
        changes regarding write of the last partition size brings the
    module back to
        it's functional state.

    Fixes: 3719c17e1816 ("wlcore/wl18xx: fw logger over sdio")

?

Hsmmc regression, that's

Subject: [PATCH 1/7] mmc: omap_hsmmc: Fix PM regression with deferred probe for pm_runtime_reinit

? Aha, but the patch this regression fixes does not seem to be in 4.4,
so I should be fine unless I go to 4.5.

Ok, I guess I'm trying to get it to sleep, first, then we can talk
about wakeup ;-).
