Subject: [PATCH v10 4/6] usb:common Simplify usb_decode_get_set_descriptor function.
Date: Sun, 21 Jul 2019 19:32:17 +0100 [thread overview]
Message-ID: <1563733939-21214-5-git-send-email-pawell@cadence.com> (raw)
In-Reply-To: <1563733939-21214-1-git-send-email-pawell@cadence.com>
Patch moves switch responsible for decoding descriptor type
outside snprintf. It improves code readability a little.
