    In preparation for unconditionally passing the
    struct tasklet_struct pointer to all tasklet
    callbacks, switch to using the new tasklet_setup()
    and from_tasklet() to pass the tasklet pointer explicitly.

  • 627469e44   dmaengine: coh901318: Fix a double-lock bug ... Browse Code »

    The function coh901318_alloc_chan_resources() calls spin_lock_irqsave()
    before calling coh901318_config().
    But coh901318_config() calls spin_lock_irqsave() again in its
    definition, which may cause a double-lock bug.

    Because coh901318_config() is only called by
    coh901318_alloc_chan_resources(), the bug fix is to remove the
    calls to spin-lock and -unlock functions in coh901318_config().

    This is in preperation of moving to a callback that provides results to the
    callback for the transaction. The conversion will maintain current behavior
    and the driver must convert to new callback mechanism at a later time in
    order to receive results.

  • 77a68e56a   dmaengine: Add an enum for the dmaengine alignment constraints ... Browse Code »

    Most drivers need to set constraints on the buffer alignment for async tx
    operations. However, even though it is documented, some drivers either use
    a defined constant that is not matching what the alignment variable expects
    (like DMA_BUSWIDTH_* constants) or fill the alignment in bytes instead of
    power of two.

    Add a new enum for these alignments that matches what the framework
    expects, and convert the drivers to it.

  • 4d76bbed2   dmaengine: coh901318: fix function return types build warnings ... Browse Code »

    A recent patch that removed coh901318_control() replaced it
    with a number of pointers to existing functions, but those
    unfortunately have the wrong return type and need to be
    changed to return an 'int' with an error value rather than
    a 'void' to avoid these build warnings:

    drivers/dma/coh901318.c:2697:32: warning: assignment from incompatible pointer type
    base->dma_slave.device_config = coh901318_dma_set_runtimeconfig;
    ^
    drivers/dma/coh901318.c:2698:31: warning: assignment from incompatible pointer type
    base->dma_slave.device_pause = coh901318_pause;
    ^
    drivers/dma/coh901318.c:2699:32: warning: assignment from incompatible pointer type
    base->dma_slave.device_resume = coh901318_resume

    The coh901318_base_init function has the correct return type
    already, but needs to be marked 'static' to avoid a sparse
    warning about a missing declaration.
