From 1770d39d10dd4c7b867e8e9f88d0f23373df3773 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Mon, 25 Dec 2023 07:23:00 +0900 Subject: firewire: test: add KUnit test for device attributes The traverse over CSR space results in attributes of node and unit devices. Any test of the traverse is useful. This commit adds a skeleton of KUnit test for the purpose.
