FB: fix unsafe use of disable_irq() in mx3fb.c
mx3fb.c calls disable_irq() from a DMA callback, i.e., in an IRQ-handler context, which has always been unsafe, and became deadly after the merge of threaded interrupt handler support. Use disable_irq_nosync() instead. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
