From 0984d159c8ad6618c6ebd9f00bc3f374fa52bc35 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 25 Jul 2016 15:39:53 +0200 Subject: sound: oss: Use kernel_read_file_from_path() for mod_firmware_load() Since recently we have kernel_read_file_from_path(), and it's doing the same thing as our own home-baked mod_firmware_load(). Let's use the official API function and clean up the old code.
