Subject: [PATCH] usb: avoid needless address-taking of function parameters
Date: Wed, 08 Oct 2008 01:10:13 -0700 [thread overview]
Message-ID: <1223453413.8195.91.camel@brick> (raw)
There's no need to take the address of the function params or local variables
when the direct value byteswapping routines are available.
