[PATCH v2 19/33] clk: clk_stm32h7: migrate trace to dev and log macro
Patrick Delaunay

Fri Nov 6 19:01:47 CET 2020
Change debug and pr_ macro to dev macro and define LOG_CATEGORY.
Remove the "%s:" __func__ header as it is managed by dev macro
(dev->name is displayed) or log macro (CONFIG_LOGF_FUNC).
