Which is the correct license?

[license.txt](https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/license.txt) says it's licensed under MIT license.

But, almost all examples says they are licensed under BSD license:

- https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/examples/HT16K33/HT16K33.ino
- https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/examples/sevenseg/sevenseg.ino
- https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/examples/wavface/wavface.pde
- https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/examples/bargraph24/bargraph24.ino
- https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/examples/bicolor8x8/bicolor8x8.pde
- https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/examples/matrix16x8/matrix16x8.ino
- https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/examples/matrix8x8/matrix8x8.ino
- https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/examples/minimatrix16x8/minimatrix16x8.ino
- https://github.com/adafruit/Adafruit_LED_Backpack/blob/master/examples/roboface/roboface.pde

is MIT license applied this repository *except* these files?

Start by comparing license.txt with the license notices in the listed examples under examples/HT16K33, sevenseg, wavface, bargraph24, bicolor8x8, matrix16x8, matrix8x8, minimatrix16x8, and roboface. Confirm the licensing scope for the repository and those files, then update the relevant license documentation so the answer is explicit.
