You have understood correctly. The mentioned patch did not change
anything, whether or not I engaged the workaround.

That said, to my eyes, the patch looks like it might be related. There
are some mentions of broadcom quirks and UHS mode in there. But the
bottom line is that I didn't experience any difference with the patch.

  Triaged

Bug description:
  I have a Broadcom BCM57765/57785 SDXC/MMC Card Reader internally in my
  MacBook Pro Retina 13", and it does not work.

  WORKAROUND:
    1. Add the following to /etc/modprobe.d/sdhci: options sdhci debug_quirks2=4
    2. Re-generate initrd: sudo update-initramfs -u -k all
    3. Reboot (or reload sdhci module: sudo rmmod sdhci-pci sdhci ; sudo modprobe sdhci ; sudo modprobe sdhci-pci)
