genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51Z

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

dmaengine :ipu: change ipu_irq_handler() to remove compile warning

dmaengine: kill off set_irq_flags usage

2015-08-19T16:01:58Z

set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

dmaengine: ipu: Consolidate duplicated irq handlers

2015-08-06T03:00:57Z

The functions irq_irq_err and ipu_irq_fn are identical plus/minus the comments. Remove one. Signed-off-by: Thomas Gleixner Cc: Vinod Koul Cc: Dan Williams Cc: dmaengine@vger.kernel.org Signed-off-by: Vinod Koul

dmaengine: ipu: Prepare irq handlers for irq argument removal

2015-08-06T03:00:57Z

The irq argument of most interrupt flow handlers is unused or merily used instead of a local variable. The handlers which need the irq argument can retrieve the irq number from the irq descriptor. Search and update was done with coccinelle and the invaluable help of Julia Lawall.

dmaengine: ipu: Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc

2015-07-16T13:11:18Z

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we already have a pointer to corresponding irq_desc. This is also a preparation for the removal of the 'irq' argument from interrupt flow handlers.

dmaengine: ipu: Consolidate chained IRQ handler install/remove

2015-07-16T13:10:52Z

Chained irq handlers usually set up handler data as well. We now have a function to set both under irq_desc->lock. Replace the two calls with one. Search and conversion was done with coccinelle.
