The patch titled
spi core: stop updating dev->power.power_state
has been removed from the -mm tree. Its filename was
spi-core-stop-updating-dev-powerpower_state.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: spi core: stop updating dev->power.power_state
From: David Brownell <david-b@xxxxxxxxxxx>
Don't update dev->power.power_state any more in the SPI core. The only
reason to update this scheduled-to-be-removed field was to make the
already-removed /sys/devices/.../power/state files work better.
