kobject: kset_uevent_ops: make name() callback take a const *

2022-11-22T16:34:52+00:00

The name() callback in struct kset_uevent_ops does not modify the
kobject passed into it, so make the pointer const to enforce this
restriction.  When doing so, fix up the single existing name() callback
to have the correct signature to preserve the build.

kobject: kset_uevent_ops: make filter() callback take a const *

2022-11-22T16:34:46+00:00

The filter() callback in struct kset_uevent_ops does not modify the
kobject passed into it, so make the pointer const to enforce this
restriction.  When doing so, fix up all existing filter() callbacks to
have the correct signature to preserve the build.

kobject: make kobject_get_ownership() take a constant kobject *

2022-11-22T16:34:29+00:00

The call, kobject_get_ownership(), does not modify the kobject passed
into it, so make it const.  This propagates down into the kobj_type
function callbacks so make the kobject passed into them also const,
ensuring that nothing in the kobject is being changed here.

This helps make it more obvious what calls and callbacks do, and do not,
modify structures passed to them.

driver core: Use kstrtobool() instead of strtobool()

2022-11-10T17:34:47+00:00

strtobool() is the same as kstrtobool().
However, the latter is more used within the kernel.

In order to remove strtobool() and slightly simplify kstrtox.h, switch to
the other function name.

While at it, include the corresponding header file ()

driver core: remove devm_device_remove_group()

2022-11-10T17:27:54+00:00

There is no in-kernel user of this function, so it is not needed anymore
and can be removed.

driver core: class: make namespace and get_ownership take const *

2022-11-09T14:49:32+00:00

The callbacks in struct class namespace() and get_ownership() do not
modify the struct device passed to them, so mark the pointer as constant
and fix up all callbacks in the kernel to have the correct function
signature.

This helps make it more obvious what calls and callbacks do, and do not,
modify structures passed to them.

driver core: use IS_ERR_OR_NULL() helper in device_create_groups_vargs()

2022-09-24T13:00:38+00:00

Use IS_ERR_OR_NULL() helper in device_create_groups_vargs() to simplify code
and improve readiblity. No functional change.

This reverts commit 71066545b48e4259f89481199a0bbc7c35457738.

It causes boot problems on some systems, so revert it for now until it
