Zeeb AuthorDate: 2022-10-22 17:40:17 +0000 Commit: Bjoern A. Zeeb CommitDate: 2022-10-22 17:40:17 +0000 iwlwifi: prepare to support debugfs Import two files left out initially from the driver needed for debugfs support [1]. Adjust the driver further to make it compile on FreeBSD. This is currently turned off and needs more LinuxKPI/lindebugfs work. Being in the tree will allow us to collaboratively work on it and then we can enable it for good.
