[PATCH AUTOSEL 5.13 117/189] RDMA/hfi1: Use attributes for the port sysfs

Sasha Levin
2021-07-06T11:22:58Z

From: Jason Gunthorpe <jgg@nvidia.com>

[ Upstream commit 8f1708f19f919135a5d7eddcdccc15b7fd7d524d ]

hfi1 should not be creating a mess of kobjects to attach to the port
kobject - this is all attributes. The proper API is to create an
attribute_group list and create it against the port's kobject.
