From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> [ Upstream commit c3efcedd272aa6dd5929e20cf902a52ddaa1197a ] KS8851_MLL selects MICREL_PHY, which depends on PTP_1588_CLOCK_OPTIONAL, so make KS8851_MLL also depend on PTP_1588_CLOCK_OPTIONAL since 'select' does not follow any dependency chains. Fixes kconfig warning and build errors: WARNING: unmet direct dependencies detected for MICREL_PHY Depends on [m]: NETDEVICES [=y] && PHYLIB [=y] && PTP_1588_CLOCK_OPTIONAL [=m] Selected by [y]: - KS8851_MLL [=y] && NETDEVICES [=y] && ETHERNET [=y] && NET_VENDOR_MICREL [=y] && HAS_IOMEM [=y] ld: drivers/net/phy/micrel.o: in function `lan8814_ts_info': micrel.c:(.text+0xb35): undefined reference to `ptp_clock_index' ld: drivers/net/phy/micrel.o: in function `lan8814_probe': micrel.c:(.text+0x2586): undefined reference to `ptp_clock_register' Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Cc: "David S.
