This patch needs to be picked up for stable as 4.9 is currently broken w.r.t.
MMC on Qualcomm platforms.

Fixes: d84be51d1c1d ("mmc: sdhci-msm: Enable few quirks")

Andy Gross

I did a quick investigation around this.

So for some reason Greg decided to pick up the original commit,
a0e3142869d2 ("mmc: sdhci-msm: Enable few quirks"), for 4.9 stable
[1], even if that patch wasn't sent or tagged for stable.
It was a mistake, as simple as that - and I should also have spotted
it when Greg posted his stable-review series, sorry.

For clarification, the original commit a0e3142869d2 ("mmc: sdhci-msm:
Enable few quirks"), is present in 4.10 together with $subject patch.
So the regression is present only in 4.9 stable.

Greg, can you pick up @subject patch for stable according to Andy's
suggestion or you want some of us to re-post it to stable?

Sorry about this.  What git commit should I take for this from Linus's
tree for the 4.9-stable tree?  Or if there isn't one, I'll be glad to
just revert this.


Thanks Greg and Ulf,

A revert of d84be51d1c1d ("mmc: sdhci-msm: Enable few quirks") would be
the best solution.

The other option is to pick 80031bdeb764 ("mmc: sdhci-msm: Add
get_min_clock() and get_max_clock() callback").

I've reverted it now, thanks.
Thanks Ulf, Greg and all.

Regards
Ritesh
