From: Chao Xie <redacted> For some SOCes use mmp_pdma, they have several dma controllers sharing same irq. So add IRQF_SHARED to flag when request irq. It can make multiple controllers share the same irq. Signed-off-by: Chao Xie <redacted> --- drivers/dma/mmp_pdma.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
