Subject: [PATCH net-next] net: ax88796c: fix -Wpointer-bool-conversion warning

From: Arnd Bergmann <arnd@...db.de>

ax_local->phydev->advertising is an array, not a pointer, so
clang points out that checking for NULL is unnecessary:

drivers/net/ethernet/asix/ax88796c_main.c:851:24: error: address of array 'ax_local->phydev->advertising' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
        if (ax_local->phydev->advertising &&
            ~~~~~~~~~~~~~~~~~~^~~~~~~~~~~ ~~
