Commit Message

Gilad Ben-Yossef Nov. 7, 2017, 9:39 a.m.
The driver was using a function naming scheme
including common prefixes for driver global
functions based on the code module they came from.

The combination of long names with long common
prefixes made the whole thing hard for a human
to parse.

Make the semantic change of switching to simple
function naming scheme and shorten function
name for better readabilty.
