[PATCH 02/21] clk: remove unneeded 'fast_io' parameter in regmap_config

Should drivers/clk/sprd/common.c also be updated as well?

Thank you!

> Should drivers/clk/sprd/common.c also be updated as well?

Yes. I wrote in the cover-letter that a few occasions couldn't be
automated with my coccinelle script because of the indirection. I will
fix the remaining few ones manually, but I didn't get to that until now.

Happy hacking,
