Subject: NFC: nci: Add RF NFCEE action notification support
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a41bb8448ebaebe1d0d9a268d340fad73c247e09;p=linux-beck.git

NFC: nci: Add RF NFCEE action notification support

The NFCC sends an NCI_OP_RF_NFCEE_ACTION_NTF notification
to the host (DH) to let it know that for example an RF
transaction with a payment reader is done.
For now the notification handler is empty.
