If anyone has any objections, please let me know. ------------------ From: Runyu Xiao [ Upstream commit 995b96380ba5d98131acc162608da3538e1395d8 ] The driver obtains an IRQ number from device tree but never requests an IRQ handler for the PCM6240 device. Removing the device must not pass that number to free_irq(). Leave IRQ ownership to a matching request path if one is added later.
