This patch adds supporting utility functions
for selftest. The intention is to share the self
test code between different drivers.

Supported test cases include:
1. dma_map_single
2. streaming DMA
3. coherent DMA
4. scatter-gather DMA



+       u32 i, j = 0;

unsigned int

why?

Is i or j is going to be used for HW communication? No? What about
assignment to a values of type u32? No? Plain counters? Use plain
types.

OK. I did an internal code review before posting the patch. Nobody complained about iterator types. I am trying to find what goes as a good practice vs. what is personal style.


It's actually comment about your all patches I saw last week.

+       int err = 0;
+       int ret;


Any reason to have two instead of one of similar meaning?


removed ret

Don't forget to check if it's redundant assignment (check in all your
patches as well).


I'll look.
