It seems that it has now been superseded by http://thread.gmane.org/gmane.linux.kernel.mmc/24371

Will those ones go in 3.13-rc8 and final ?

TIA

I think patch 1 in that series is better to go in 3.13 final since the issue exists
since 3.13 rc1.

Patch 2 in that series is the fix for sdhci-esdhc-imx runtime pm which is
newly added in chris/mmc-next and seems target for 3.14.

Chris,
Can we make it?

Subject: mmc patch needed for 3.13 [was Re: ARM,sdhci_esdhc_imx: INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected]

Hi Chris & Shawn,

The patch http://thread.gmane.org/gmane.linux.kernel.mmc/24371, that fixes
a bug introduced in 3.13-rc1, is not in 3.13-rc8. Any chance to get it in
3.13 final ?
