simple_open: automatically convert to simple_open() 2012-04-05T22:25:50+00:00 Stephen Boyd sboyd@codeaurora.org 2012-04-05T21:25:11+00:00 234e340582901211f40d8c732afc49f0630ecf05 Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open().
