[PATCH 6.6 065/129] pds_core: make pdsc_auxbus_dev_del() void

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Shannon Nelson <shannon.nelson@amd.com>

[ Upstream commit e8562da829432d04a0de1830146984c89844f35e ]

Since there really is no useful return, advertising a return value
is rather misleading.  Make pdsc_auxbus_dev_del() a void function.
