[PATCH v2 1/3] drm/probe-helper: Document drm_helper_hpd_irq_event() return value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The documentation of the drm_helper_hpd_irq_event() function didn't
document the value that function was returning. Add that part as well.
