[PATCH] NFC: microread: Auto-select core module

[PATCH] NFC: microread: Auto-select core module

[Jean Delvare]

As I understand it, the core nfc_microread module is useless without
either the I2C or the MEI access module. So hide NFC_MICROREAD and
select it automatically if either NFC_MICROREAD_I2C or
NFC_MICROREAD_MEI is selected.

This avoids presenting NFC_MICROREAD when neither NFC_MICROREAD_I2C
nor NFC_MICROREAD_MEI can be selected.
