Subject: [PATCH] sound: korg1212: fix if-statement empty body warnings
Date: Tue, 25 Feb 2020 21:32:49 -0800	[thread overview]
Message-ID: <91fb1e97-a773-5790-3f65-8198403341e1@infradead.org> (raw)

From: Randy Dunlap <rdunlap@infradead.org>

Fix gcc warnings when -Wextra is used by using an empty do-while
block instead of <nothing>.  Fixes these build warnings:
