If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5284007fb83ca0ae2300ce661e0537028d3cd6ab Author: Jinjie Ruan <ruanjinjie@xxxxxxxxxx> Date: Mon Sep 9 15:31:40 2024 +0800 spi: geni-qcom: Fix incorrect free_irq() sequence [ Upstream commit b787a33864121a565aeb0e88561bf6062a19f99c ] In spi_geni_remove(), the free_irq() sequence is different from that on the probe error path. And the IRQ will still remain and it's interrupt handler may use the dma channel after release dma channel and before free irq, which is not secure, fix it.
