Thanks for the update!

Doing this after the introduction of the common macros breaks bisection.
To avoid, that you can either convert them during the addition, or
make it a two step-operation, like was done in Linux in e.g.
commits dbfe51513aae6bac ("clk: at91: pmc: #undef field_{get,prep}()
before definition") and 0f8407a1f1c795c4 ("clk: at91: Convert to common
field_{get,prep}() helpers").

when I'm talking to journalists I just say "programmer" or something like that.
