[<gregkh@linuxfoundation.org>]

This is a note to let you know that I've just added the patch titled

    platform: thinkpad_acpi: convert to use DRIVER_ATTR_RO/RW

to my driver-core git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git
in the driver-core-next branch.

The patch will show up in the next release of the linux-next tree

Subject: platform: thinkpad_acpi: convert to use DRIVER_ATTR_RO/RW

We are trying to get rid of DRIVER_ATTR(), and the thinkpad_acpi
driver's attributes can be trivially changed to use DRIVER_ATTR_RO() and
DRIVER_ATTR_RW().
