Subject: [PATCH 03/10] platform/x86: toshiba_acpi: bind registration of miscdev object to parent
Date: Wed, 24 Mar 2021 14:55:41 +0200 [thread overview]
Message-ID: <20210324125548.45983-4-aardelean@deviqon.com> (raw)
In-Reply-To: <20210324125548.45983-1-aardelean@deviqon.com>
This change moves the registration of the Toshiba ACPI miscdev to be
handled by the devm_add_action_or_reset() hook. This way, the miscdev will
be unregistered when the reference count of the parent device object goes
to zero.
This also changes the order of cleanup in toshiba_acpi_remove(), where the
miscdev was deregistered first. Now it will be deregistered right before
the toshiba_acpi_dev object is free'd.
