[PATCH v2 09/33] mmc: stm32_sdmmc2: migrate trace to dev and log macro

Patrick Delaunay patrick.delaunay at st.com
Fri Nov 6 19:01:37 CET 2020


Define LOG_CATEGORY, use dev_ macro when it is possible.
Remove the "%s:" __func__  header as it is managed by dev macro
(dev->name is displayed) or log macro (CONFIG_LOGF_FUNC).
