Sashiko AI review found no new issues in this patch, but noticed 1 related pre-existing issue it does not introduce: - [High] mtd: rawnand: tegra: unclocked register access in tegra_nand_irq() [1] -- commit 6164eede324ed80f4bb2c1a0eea0f8635af28e57 Author: James Hilliard mtd: rawnand: tegra: retain open-handle state on removal This commit switches the Tegra NAND chip and controller allocations to reference-counted release callbacks and disconnects the chip before suspending the controller on removal. > diff --git a/drivers/mtd/nand/raw/tegra_nand.c b/drivers/mtd/nand/raw/teg= ra_nand.c > index 7f9eb5f042a7e..da7791741b9d4 100644 > --- a/drivers/mtd/nand/raw/tegra_nand.c > +++ b/drivers/mtd/nand/raw/tegra_nand.c [ ... ] > @@ -1232,10 +1254,11 @@ static void tegra_nand_remove(struct platform_dev= ice *pdev) > =20 > WARN_ON(mtd_device_unregister(mtd)); > =20 > - nand_cleanup(chip); > + nand_disconnect(chip); > =20 > pm_runtime_put_sync_suspend(ctrl->dev); > pm_runtime_force_suspend(ctrl->dev); > + mtd_put_master(mtd); > } [Severity: High] This problem wasn't introduced by this patch, but can tegra_nand_irq() access unclocked registers after pm_runtime_force_suspend() [1]? tegra_nand_probe() registers tegra_nand_irq() with devm_request_irq(), so the IRQ remains active until devres cleanup runs after tegra_nand_remove() (and after the err_put_pm path in tegra_nand_probe()) returns. In the meantime, pm_runtime_force_suspend() disables ctrl->clk, and any pending or spurious interrupt before devres frees the IRQ causes tegra_nand_irq() to read ISR and DMA_MST_CTRL while the controller is unclocked, triggering an asynchronous external abort on Tegra.
