Subject: [PATCH] net: bcmgenet: Remove the unused function
Date:   Fri,  9 Dec 2022 11:37:23 +0800

The function dmadesc_get_addr() is defined in the bcmgenet.c file, but
not called elsewhere, so remove this unused function.

drivers/net/ethernet/broadcom/genet/bcmgenet.c:120:26: warning: unused function 'dmadesc_get_addr'.
