Subject: [PATCH v3 6/8] hwmon: (k10temp) Reduce k10temp_get_ccd_support()
 parameters

Currently, k10temp_get_ccd_support() takes as input "pdev" and "data".
However, "pdev" is already included in "data". Furthermore, the "pdev"
parameter is no longer used in k10temp_get_ccd_support(), since its use
was moved into read_ccd_temp_reg().

Drop the "pdev" input parameter as it is no longer needed.

No functional change is intended.
