V2.0.14 Fails to compile for nRF52 MCU

[beegee-tokyo]

Subject of the issue

Compilation for nRF52 BSP fails with error.

Your workbench

• GNSS breakout: RAKwireless WisBlock RAK12500 HW version 1.0
• MCU board:
  • WisBlock RAK4631 WisCore
  • MCU & GNSS module plugged into Sensor slot of RAKwireless WisBlock RAK5005-O
• Powered over USB
• Compilation works with Library version V2.0.13

Steps to reproduce

Compile any example for any nRF52 board using Adafruit nRF52 Arduino BSP.

Expected behavior

Compilation error should not happen.

Actual behavior

Compilation error

Switching back to V2.0.13 solves the problem and compilation works without problems.
