dmaengine: ppc4xx: remove unused variable `rval'

2021-11-25T05:17:08Z

The variable used for returning status in `ppc440spe_adma_dma2rxor_prep_src' function is never changed and this function just need to return 0. Thus, the `rval' can be removed and return 0 from `ppc440spe_adma_dma2rxor_prep_src'.

dmaengine: ppc4xx: convert tasklets to use new tasklet_setup() API

2020-09-18T06:49:07Z

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.

dmaengine: ppc4xx: Use scnprintf() for avoiding potential buffer overflow

2020-03-11T09:40:45Z

Since snprintf() returns the would-be-output size instead of the actual output size, the succeeding calls may go beyond the given buffer limit. Fix it by replacing with scnprintf().
