Subject: [PATCH v2] irqchip: imx-irqsteer: Convert to devm_pm_runtime_enable()
Date: Wed, 29 Jul 2026 19:14:16 -0300	[thread overview]
Message-ID: <20260729221416.499781-1-festevam@gmail.com> (raw)

imx_irqsteer_probe() enables runtime PM, but imx_irqsteer_remove()
does not disable it.

Consequently, runtime PM remains enabled after unbinding the device,
and rebinding it triggers:

Unbalanced pm_runtime_enable!

Use devm_pm_runtime_enable() to automatically disable runtime PM when
the device is removed.

Fixes: 4730d2233311 ("irqchip/imx-irqsteer: Add runtime PM support")
