From 7ec827b9465c427511f05bab02dddbcfdd4ecc53 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 23 Nov 2020 09:53:18 +0100 Subject: [PATCH] ALSA: usb-audio: Drop debug.h The file debug.h contains a simple macro for debug prints, and it's used only in two places, the format parser and the hw_params rules. The former actually should print a more informative message instead, so the only users are the hw_parmas rules. This patch moves the contents of debug.h into the hw_params rules local code and remove the unneeded includes. Also, the debug print in the format parser is replaced with the information print with more useful information, and the raw printk() call is replaced with pr_debug().
