X-Git-Tag: v4.8-rc1~117^2^2~15
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=898dbbf65f1d041d5c1b29a0880286e26fac5076;p=users%2Fjedix%2Flinux-maple.git

dmaengine: omap-dma: explicitly freeup irq

dmaengine device should explicitly call devm_free_irq() when using
devm_request_irq().

The irq is still ON when devices remove is executed and irq should be
quiesced before remove is completed.
