wifi: mac80211: fix incorrect type for ret

Liao Yuanhong · jmberg-intel · commit a33b375ab5b3 · 2025-08-26T13:46:48.000+02:00
The variable ret is declared as a u32 type, but it is assigned a value of -EOPNOTSUPP. Since unsigned types cannot correctly represent negative values, the type of ret should be changed to int.
