NFC: trf7970a: Don't turn on RF if there is already an RF field Currently, the trf7970a driver blindly turns on its RF field when configuring its framing. This isn't a good idea if there is already a device generating an RF field. Instead, check if there is already an RF field present before turning on this device's RF field and, if there is, return EBUSY. Signed-off-by: Mark A.
