Subject: spi: pxa2xx: limit reaches -1
From: Roel Kluin <roel.kluin@xxxxxxxxx>
On line 944 the return value of flush() is considered as a boolean,
but limit reaches -1 upon timeout which evaluates to true.
On 540, 594, 720 the same occurs for wait_ssp_rx_stall()
On 536 the same occurs for wait_dma_channel_stop()
