[PATCH net] net: dsa: motorcomm: Fix function parameter types

From: David Yang

Date: Mon Oct 26 2026 - 04:33:58 EST


yt921x_fdb_add_index_in12() mistakenly takes the two register images
as u16, while all registers are 32-bit wide, silently losing the upper
half. Widen the parameters to u32.

Fixes: 186623f4aa72 ("net: dsa: yt921x: Add support for Motorcomm YT921x")
