History
Lars Poeschel 1e37be7d27 nfc: pn533: pn533_phy_ops dev_[up, down] return int 
Change dev_up and dev_down functions of struct pn533_phy_ops to return
int. This way the pn533 core can report errors in the phy layer to upper
layers.
The only user of this is currently uart.c and it is changed to report
the error of a possibly failing call to serdev_device_open.
