parisc: pdc_stable: Fix memory leak in pdcs_register_pathentries

2022-01-21T21:48:54+00:00

kobject_init_and_add() takes reference even when it fails.
According to the doc of kobject_init_and_add()：

   If this function returns an error, kobject_put() must be called to
   properly clean up the memory associated with the object.

Fix memory leak by calling kobject_put().

parisc: pdc_stable: use default_groups in kobj_type

2022-01-07T00:29:22+00:00

There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field.  Move the parisc pdc_stable sysfs code to use default_groups
field which has been the preferred way since aa30f47cf666 ("kobject: Add
support for default attribute groups to kobj_type") so that we can soon
get rid of the obsolete default_attrs field.

parisc: Move pci_dev_is_behind_card_dino to where it is used

2021-09-09T10:44:31+00:00

parisc build test images fail to compile with the following error.

drivers/parisc/dino.c:160:12: error:
	'pci_dev_is_behind_card_dino' defined but not used

Move the function just ahead of its only caller to avoid the error.
