A cleanup patch left one local variable without a reference:
drivers/staging/octeon/ethernet-rx.c:339:28: warning: unused variable 'priv'
[-Wunused-variable]
This removes the declaration too.

net_device")

This series adds support for lvds display, touchscreen nodes on dts for
Engicam i.CoreM6 Quad boards along with selecting few touchscreen driver
configs to imx_v6_v7_defconfig so-that select by default.

Read back the register after setting or clearing a reset bit to make
sure that the changes are applied to the reset controller hardware.
Theoretically, this avoids the write to stay stuck in a store buffer
during the delay of an assert-delay-deassert sequence, and makes sure
that the reset really i

Reset operations for simple reset controllers with reset lines that can
be controlled by toggling bits in (mostly) contiguous register ranges
using read-modify-write cycles under a spinlock. So far this covers the
socfpga, stm32, and sunxi drivers.

klp_mutex is shared between core.c and transition.c, and as such would
rather be properly located in livepatch.h so that we don't have to play
'extern' games from .c sources.
This also silences sparse warning (wrongly) suggesting that klp_mutex
should be defined static.
