Anatolij Gustschin 70aa610959 mmc: mxcmmc: fix race conditions for host->req and host->data access ... mxcmci_dma_callback() is invoked by DMA drivers in soft-irq context and can be interrupted by the mxcmci_irq() interrupt which can finish the mmc request or data transfer and set host->req or host->data pointers to NULL. Then mxcmci_data_done() crashes with a null pointer dereferences. Protect all accesses to host->req and host->data by spin locks. Also check host->data pointer in mxcmci_watchdog() before dereferencing it.
