# drm\_irq\_uninstall(9)

uninstall the IRQ handler

## NAME

drm\_irq\_uninstall - uninstall the IRQ handler

## SYNOPSIS

**int drm\_irq\_uninstall(struct drm\_device \*** *dev***);**

## ARGUMENTS

*dev*

DRM device

## DESCRIPTION

Calls the driver's **irq\_uninstall** function and unregisters the IRQ handler. This should only be called by drivers which used **drm\_irq\_install** to set up their interrupt handler. Other drivers must only reset drm\_device-\>irq\_enabled to false.

Note that for kernel modesetting drivers it is a bug if this function fails. The sanity checks are only to catch buggy user modesetting drivers which call the same function through an ioctl.

## RETURNS

Zero on success or a negative error code on failure.
