Subject: dmaengine: txx9dmac: explicitly freeup irq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=debc4849007517be8f03a199ea29dc3f797c329e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

dmaengine: txx9dmac: 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.
