Subject: [PATCH] Work around CPU stalls in the imx-sdma driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Replace spinlocks with raw spinlocks. This prevents preemption during
the spinlock's critical section, as is the case on non PREEMPT_RT kernels.
Without this patch, the following error can occur, for example when
using the audio codec on an i.MX6Q SabreSD board:
