+Subject: [PATCH 30/65] spi/m68knommu: Coldfire QSPI platform support
+
+After grabbing a msg from the msgq, the mcfqspi_work function calls
+list_del_init on the mcfqspi->msgq which unintentionally deletes the rest
+of the list before it can be processed. If qspi call was made using
+spi_sync, this can result in a process hang.
