Subject: [PATCH v4 18/18] gpiolib: Clean up headers
There is a few things done:
- include only the headers we are direct user of
- when pointer is in use, provide a forward declaration
- add missing headers
- group generic headers and subsystem headers
- sort each group alphabetically
Signed-off-by: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>
