Subject[RFC PATCH 5/9] IB/hfi1: convert to debugfs_file_get() and -put()
Date
Convert all calls to the now obsolete debugfs_use_file_start() and
debugfs_use_file_finish() to the new debugfs_file_get() and
debugfs_file_put() API.

Fixes: 49d200deaa68 ("debugfs: prevent access to removed files' private
data")
