same here! I'm pretty sure I connected the GPIO pins correctly (checked twice), enabled SPI and rebooted the pi. got two SPI devices:

root@raspberrypi:/home/pi# ls /dev/spi*
/dev/spidev0.0  /dev/spidev0.1

using raspian jessi w/ kernel 4.1.13

haha - realized that I had connected the MFRC522 to the RPI2 using a pic of RPI1 wasted two hours, works fine now
