Subject: [PATCH 6/9] ACPI: EC: move acpi_ec_start() after acpi_ec_add()
Date: Fri, 19 Jun 2009 15:32:04 -0600 [thread overview]
Message-ID: <20090619213204.18001.78691.stgit@bob.kio> (raw)
In-Reply-To: <20090619213038.18001.16533.stgit@bob.kio>
This patch rearranges ec_install_handlers() and acpi_ec_start() so
acpi_ec_start() ends up just after acpi_ec_add(). A subsequent patch
will merge them.
Code movement only; no functional change.
