[PATCH 2/2] coccinelle: semantic patch for simple_open()

[Stephen Boyd <sboyd@xxxxxxxxxxxxxx>]

Find instances of an open-coded simple_open() and replace them
with calls to simple_open().

This seems to eat the definition of simple_open() as well. Is there
a way to say only remove both the function and the reference to
the function so that libfs survives?
