net: sky2: initialize return of gm_phy_read
clang static analysis flags this garbage return drivers/net/ethernet/marvell/sky2.c:208:2: warning: Undefined or garbage value returned to caller [core.uninitialized.UndefReturn] return v; ^~~~~~~~ static inline u16 gm_phy_read( ... { u16 v; __gm_phy_read(hw, port, reg, &v); return v; } __gm_phy_read can return without setting v. So handle similar to skge.c's gm_phy_read, initialize v. Signed-off-by: Tom Rix <trix@redhat.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
