Agreed, the wcss_wlan[210]_groups arrays and functions are unused prior
to this patch nor are pins 40/41/42 part of wcss_wlan_groups (which only
contains 43 and 44).  Same for the BT fix, the pingroup for pin 48 is
clearly wcss_bt and there's none for pin 88.

You could have made that more clear in the commit message though (and
I'm not even sure if pinctrl allows the pins to be used when the groups
are misaligned like this, at least there's a fixes: tag), but for the
change itself:
