    Subject[PATCH] Remove an unused variable from the Intel I/OAT DMA engine driver
    Date

    The 'u16 chanctrl' variable in
    drivers/dma/ioatdma.c::ioat_dma_free_chan_resources() is completely
    unused and gcc quite rightfully warns about it:

    drivers/dma/ioatdma.c:247: warning: unused variable 'chanctrl'

    This patch removes the unused variable and silences the warning.
