Subject: [PATCH 03/36] usb: gadget: s3c: use platform resources
Date: Thu, 10 Oct 2019 22:29:47 +0200 [thread overview]
Message-ID: <20191010203043.1241612-3-arnd@arndb.de> (raw)
Message-ID: <20191010202947.RzjKA3lnWoliftsRSNutC3M2_J5ecf-5foenmB0YpUI@z> (raw)
In-Reply-To: <20191010203043.1241612-1-arnd@arndb.de>
The resources are correctly initialized, so just use them
instead of relying on hardcoded data from platform headers.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
