sh: superhyway: Simplify check in remove callback

2021-08-05T12:37:03Z

The driver core only calls a remove callback when the device was successfully bound (aka probed) before. So dev->driver is never NULL. (And even if it was NULL, to_superhyway_driver(NULL) isn't ...)

bus: Make remove callback return void

2021-07-21T09:53:42Z

The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

sh: superhyway: use dev_groups and not dev_attrs for bus_type

2017-06-09T09:00:46Z

The dev_attrs field has long been "depreciated" and is finally being removed, so move the driver to use the "correct" dev_groups field instead for struct bus_type. Cc: Yoshinori Sato Cc: Rich Felker Cc: Greg Kroah-Hartman Cc: Signed-off-by: Greg Kroah-Hartman

drivers: Initialize resource entry to zero

2016-01-30T08:49:58Z

I/O resource descriptor, 'desc' in struct resource, needs to be initialized to zero by default. Some drivers call kmalloc() to allocate a resource entry, but do not initialize it to zero by memset(). Change these drivers to call kzalloc(), instead. Signed-off-by: Toshi Kani Signed-off-by: Borislav Petkov Acked-by: Alexandre Bounine Acked-by: Helge Deller Acked-by: Rafael J.

[PATCH] superhyway: multiple block support and VCR rework

2005-11-07T15:53:28Z

This extends the API somewhat to allow for platform-specific VCR reading and writing. Some platforms (like SH4-202) implement the VCR in a split VCRL and VCRH, but end up being in reverse order or have other quirks that need to be dealt with, so we add a set of superhyway_ops per-bus to accomodate this. We also have to extend the per-device resources somewhat, as some devices now conveniently split control and data blocks. So we allow a platform to register its set of SuperHyway devices via superhyway_add_devices() with the control block always ordered as the first resource (as this is the one that userspace cares about).
