Subject: [PATCH] usb: musb: remove redundant stack buffers
Date: Thu, 4 Aug 2016 20:58:18 +0200 [thread overview]
Message-ID: <1470337098-29111-1-git-send-email-linux@rasmusvillemoes.dk> (raw)
aDate is always the empty string, so entirely pointless. The aRevision
formatting might as well be done as part of the pr_debug() call - that
also avoids it altogether if pr_debug is compiled out.
