Subject: [PATCH 11/22] OMAP clock: rearrange clock.h structure order
Date: Mon, 22 Dec 2008 23:38:37 -0700 [thread overview]
Message-ID: <20081223063836.8542.697.stgit@localhost.localdomain> (raw)
In-Reply-To: <20081223063709.8542.82882.stgit@localhost.localdomain>
From: Russell King <rmk@dyn-67.arm.linux.org.uk>
... to eliminate unnecessary padding. We have rather a lot of these
structures, so eliminating unnecessary padding results in a saving of
1488 bytes.
[paul@pwsan.com: updated against current linux-omap clock tree, now saves
1512 bytes on OMAP3 builds]
