[PATCH 4.14 074/161] net: dsa: LAN9303: select REGMAP when LAN9303 enable

[Greg Kroah-Hartman]

From: Mao Wenan <maowenan@xxxxxxxxxx>

[ Upstream commit b6989d248a2d13f02895bae1a9321b3bbccc0283 ]

When NET_DSA_SMSC_LAN9303=y and NET_DSA_SMSC_LAN9303_MDIO=y,
below errors can be seen:
drivers/net/dsa/lan9303_mdio.c:87:23: error: REGMAP_ENDIAN_LITTLE
undeclared here (not in a function)
  .reg_format_endian = REGMAP_ENDIAN_LITTLE,
drivers/net/dsa/lan9303_mdio.c:93:3: error: const struct regmap_config
has no member named reg_read
  .reg_read = lan9303_mdio_read,

It should select REGMAP in config NET_DSA_SMSC_LAN9303.

Fixes: dc7005831523 ("net: dsa: LAN9303: add MDIO managed mode support")
