Revision:
6:c1f162fd7777
Parent:
0:a3ea811f80f2 
Fixed Error with code not compiling due to an issue with there not being a (uint32_t) cast of a (void) pointer. Maxim was the only mbed vendor to not have this one (uint32_t) cast in the spot it was added to. Look into public repos for similar cases.

Who changed what in which revision?
