[PATCH v3 0/2] Add an API for edac device, for mulriple errors

[PATCH v3 0/2] Add an API for edac device, for mulriple errors

[Hanna Hawa]

Add an API for EDAC device to report for multiple errors, and move the
old report function to use the new API.

Changes from v2:
----------------
- Remove copy of edac_device_handle_*() functions, modify the existing
functions.

Changes from v1:
----------------
- use 'unsigned int' instead of u16
- update variable name to be count
- remove WARN_ON and simply exit if count is zero
- add inline functions in header file

  edac: move edac_device_handle_*() API functions to header
