Changes in v3: - removed already applied patch "Factor out handle_bad_msg" - avoid inner looping by making the hardware retrigger on "forgotten" IRQ sources - added acked/reviewed tags Changes in v2: - factored out handle_bad_msg (Andy) - reordered code in patch 3, avoiding unneeded pci_free_irq_vectors (Andy) Jan Jan Kiszka (2): spi: pxa2xx: Prepare for edge-triggered interrupts spi: pca2xx-pci: Allow MSI drivers/spi/spi-pxa2xx-pci.c | 8 +++++++- drivers/spi/spi-pxa2xx.c | 3 +++ 2 files changed, 10 insertions(+), 1 deletion(-) -- 2.1.4
