Hi, Jingoo. did you test with your patch? It didn't work. And we don't maintain the sdhci_s3c_notify_change(). Instead, we can use the API of slot-gpio and mmc_of_parse(). https://patchwork.kernel.org/patch/4239541/ Best Regards, Jaehoon Chung On 05/30/2014 12:56 PM, Jingoo Han wrote: > The card tasklet was removed by the commit 3560db8 (mmc: sdhci: > push card_tasklet into threaded irq handler).
