[PATCH v1] drm/i915/gt: 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.
