Reading from the DEV_ID register without a consistent value to compare it to isn't useful. There isn't a way to verify the match data ID is the same ID read from the DEV_ID device register. 0xF0 isn't a DEV_ID value consistent across TPS65219 NVM configurations. For TPS65215, there is a consistent value in bits 5-0 of the DEV_ID register. However, there are other error checks in place within probe() that apply to both PMICs rather than keeping this isolated check for one PMIC.
