wifi: mac80211: fix incorrect type for ret

Liao Yuanhong · gregkh · commit 1f97f6cf81f7 · 2025-09-25T10:58:50.000+02:00
[ Upstream commit a33b375 ] 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.
