[PATCH 1/5] drm/nouveau: Prevent RPM callback recursion in suspend/resume paths
...the stack trace you've posted could be resolved using
the technique I used in d61a5c106351 by adding the following to
include/linux/pm_runtime.h:
static inline bool pm_runtime_status_suspending(struct device *dev)
{
return dev->power.runtime_status == RPM_SUSPENDING;
}
static inline bool is_pm_work(struct device *dev)
{
struct work_struct *work = current_work();
return work && work->func == dev->power.work;
}
Then adding this to nvkm_i2c_aux_acquire():
struct device *dev = pad->i2c->subdev.device->dev;
if (!(is_pm_work(dev) && pm_runtime_status_suspendin...
