This is an experimental automated report about issues detected by Coverity
from a scan of next-20191031 as part of the linux-next weekly scan project:

You're getting this email because you were associated with the identified
lines of code (noted below) that were touched by recent commits:

c656aa4c27b1 ("nfc: pn533: add UART phy driver")

Coverity reported the following:

*** CID 1487395:  Error handling issues  (CHECKED_RETURN)
/drivers/nfc/pn533/uart.c: 107 in pn532_dev_up()
101     }
103     static void pn532_dev_up(struct pn533 *dev)
104     {
105     	struct pn532_uart_phy *pn532 = dev->phy;
vvv     CID 1487395:  Error handling issues  (CHECKED_RETURN)
vvv     Calling "serdev_device_open" without checking return value (as is done elsewhere 10 out of 11 times).
107     	serdev_device_open(pn532->serdev);
108     	pn532->send_wakeup = PN532_SEND_LAST_WAKEUP;
109     }
111     static void pn532_dev_down(struct pn533 *dev)
112     {

If this is a false positive, please let us know so we can mark it as
such, or teach the Coverity rules to be smarter. If not, please make
sure fixes get into linux-next. :) For patches fixing this, please
include these lines (but double-check the "Fixes" first):
