From 806e90c4e5253095f9576113edc6fc78b2d5fec1 Mon Sep 17 00:00:00 2001 From: Jate Sujjavanich Date: Wed, 29 Sep 2010 09:44:32 -0400 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.
