[PATCH 04/46] libata: move ata_{port,link,dev}_dbg to standard dev_XXX() macros

Hannes Reinecke
2020-02-04T16:56:11Z

Use standard dev_{dbg,info,notice,warn,err} macros instead of the
hand-crafted printk helpers.
Also change the name for 'ata_device' structure to ataX:Y to be
inline with the other ata object names.
