From a228809fa6f39c3fa46ac6b929024686750f7a09 Mon Sep 17 00:00:00 2001 From: Nikolai Kondrashov Date: Sun, 8 May 2022 18:01:40 +0200 Subject: [PATCH] HID: uclogic: Move param printing to a function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move parameter printing from a format string/argument list to a function to allow printing the full parameters, which now wouldn't fit into a single print call.
