The assignment of the else and if branches is the same, so the else
here is redundant, so we remove it.

./drivers/net/wireless/realtek/rtw89/phy.c:6406:2-4: WARNING: possible condition with no effect (if == else).

Please point out the stuff like functions you are changing.

The PHY configures to corresponding MLO modes are complicated, so RF people
always add branches of phy_idx to prevent missing something, and this is
intentionally to say two cases are identical. It is fine to apply your patch,
but please add a comment to note that, like

/* for both PHY 0/1 */
