Revision:: 149:156823d33999
Parent:: targets/cmsis/TARGET_STM/TARGET_STM32L1/TARGET_XDOT_L151CC/cmsis_nvic.c@148:21d94c44109e

This updates the lib to the mbed lib v128

NOTE: This release includes a restructuring of the file and directory locations and thus some

include paths in your code may need updating accordingly.
