From: Nikita Yushchenko This avoids leak of IRQ mapping on error paths, and makes it possible to use devm_request_irq() without facing unmap-while-handler-installed issues. pata_mpc52xx's task_irq is special case since it is managed by betstcomm DMA driver. Do not use devres for it. Signed-off-

[PATCH 00/21] add and use devm_irq_of_parse_and_map()

Currently many device tree aware drivers use irq_of_parse_and_map() to get IRQ number and then devm_request_irq() to set up IRQ handler. This causes a problem for exit path and for error paths: undo action for irq_of_parse_and_map() is irq_dispose_mapping() that must not be called while IRQ handle

[PATCH 01/21] irq: add devres version of OF IRQ mapping routines

From: Nikita Yushchenko Many drivers use devres to manage their resources, and at the same time use irq_of_parse_and_map() / irq_dispose_mapping(). This creates problem on driver unload paths and on error paths: - it is invalid to call irq_dispose_mapping() while IRQ handler is still installed,
