Subject: [PATCH] usb: musb: add printf attribute to log function
Date: Mon, 21 Dec 2020 08:25:47 -0800 [thread overview]
Message-ID: <20201221162547.3756889-1-trix@redhat.com> (raw)
From: Tom Rix <trix@redhat.com>
Attributing the function allows the compiler to more thoroughly
check the use of the function with -Wformat and similar flags.
