Changes in v2: - factored out handle_bad_msg (Andy) - reordered code in patch 3, avoiding unneeded pci_free_irq_vectors (Andy) Jan Jan Kiszka (3): spi: pxa2xx: Factor out handle_bad_msg spi: pxa2xx: Prepare for edge-triggered interrupts spi: pca2xx-pci: Allow MSI drivers/spi/spi-pxa2xx-pci.c | 8 ++++++- drivers/spi/spi-pxa2xx.c | 51 +++++++++++++++++++++++++------------------- 2 files changed, 36 insertions(+), 23 deletions(-) -- 2.1.4
