Chuansheng Liu 63c211803a mmc: sdhci: Setting the host->mrq to NULL before executing tuning ... In function sdhci_request(), it is possible to do the tuning execution like below: sdhci_request() { spin_lock_irqsave(&host->lock, flags); host->mrq = mrq; ... spin_unlock_irqrestore(&host->lock, flags); <=== Here it is possible one pending finish_tasklet get running and it will operate the original mrq, and notified the mrq is done, and causes memory corruption. sdhci_execute_tuning(mmc, tuning_opcode); spin_lock_irqsave(&host->lock, flags); host->mrq = mrq; ... } In the above race place, the original mrq should not be finished wrongly, so here before unlock the spinlock, we need to set the host->mrq to NULL to avoid this case.
