Subject: [PATCH] USB-FHCI: Use a signed return type for fhci_create_ep()
Date: Sat, 19 Dec 2015 21:15:28 +0100 [thread overview]
Message-ID: <5675BAE0.2010304@users.sourceforge.net> (raw)
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 19 Dec 2015 21:10:20 +0100
The return type "u32" was used by the fhci_create_ep() function even though
it will eventually return a negative error code.
Improve this implementation detail by using the type "s32" instead.
This issue was detected by using the Coccinelle software.
