X-Git-Tag: v2.6.27-rc1~510^2~1^2~6
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=3a87208028ef59215a88a143c723ac0b83c11df0;p=linux-2.6-omap-h63xx.git

ACPI: thinkpad-acpi: minor refactor on radio switch init

Change the code of hotkey_init, wan_init and bluetooth_init a bit to make it
much easier to add some Kconfig-selected debugging code later.
