Subject: [PATCH E 14/14] OMAP clock: rearrange clock.h structure order
Date: Wed, 28 Jan 2009 12:28:07 -0700	[thread overview]
Message-ID: <20090128192804.29333.82743.stgit@localhost.localdomain> (raw)
In-Reply-To: <20090128192551.29333.82943.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]

linux-omap source commit is 64a423d87fae87608642c28393bb440b45e5e25e.
