mmc: sdhci: Check mrq->cmd in sdhci_tasklet_finish
commit b7b4d3426d2b5ecab21578eb20d8e456a1aace8f upstream.
It seems that under certain circumstances that the sdhci_tasklet_finish()
call can be entered with mrq->cmd set to NULL, causing the system to crash
with a NULL pointer de-reference.
Unable to handle kernel NULL pointer dereference at virtual address 00000000
PC is at sdhci_tasklet_finish+0x34/0xe8
LR is at sdhci_tasklet_finish+0x24/0xe8
Seen on S3C6410 system.
