Subject: [RESEND][PATCH] mtd: refactor call to request_module
Date: Mon, 8 Jul 2013 06:05:12 -0700	[thread overview]
Message-ID: <20130708130512.GA24315@www.outflux.net> (raw)

This reduces the size of the stack frame when calling request_module().
Performing the sprintf before the call is not needed.
