Subject: [PATCH 00/10] platform/x86: toshiba_acpi: move acpi add/remove to device-managed routines
Date: Wed, 24 Mar 2021 14:55:38 +0200	[thread overview]
Message-ID: <20210324125548.45983-1-aardelean@deviqon.com> (raw)

This changeset tries to do a conversion of the toshiba_acpi driver to use
only device-managed routines. The driver registers as a singleton, so no
more than one device can be registered at a time.

My main intent here is to try to convert the iio_device_alloc() and
iio_device_register() to their devm_ variants.

Usually, when converting a registration call to device-managed variant, the
init order must be preserved. And the deregistration order must be a mirror
of the registration (in reverse order).

This change tries to do that, by using devm_ variants where available and
devm_add_action_or_reset() where this isn't possible.
Some deregistration ordering is changed, because it wasn't exactly
mirroring (in reverse) the init order.

For the IIO subsystem, the toshiba_acpi driver is the only user of
iio_device_alloc(). If this changeset is accepted (after discussion), I
will propose to remove the iio_device_alloc() function.

While I admit this may look like an overzealous effort to use devm_
everywhere (in IIO at least), for me it's a fun/interesting excercise.
