[PATCH v3 19/35] dmaengine: pch_dma: convert tasklets to use new tasklet_setup() API

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
