Subject: [PATCH] drm/tilcdc: Fix irq free on unload
Date: Tue, 19 Sep 2023 10:12:50 +0300 [thread overview]
Message-ID: <20230919-lcdc-v1-1-ba60da7421e1@ideasonboard.com> (raw)
The driver only frees the reserved irq if priv->irq_enabled is set to
true. However, the driver mistakenly sets priv->irq_enabled to false,
instead of true, in tilcdc_irq_install(), and thus the driver never
frees the irq, causing issues on loading the driver a second time.
Fixes: b6366814fa77 ("drm/tilcdc: Convert to Linux IRQ interfaces")
