The series contains set of clean ups, main parts of which are:
- use ne platform_get_mem_or_io() API
- use match_string() API
Since v2:
- patch 3: rephrased commit message (Corey)
- patch 5: added a comment that array maps to enum (Corey)
- patch 5: added "ipmi" prefix to the name of the array
- patch 6: just exported array w/o moving to header (Corey)
- wrapped up cover letter
Andy Shevchenko (10):
ipmi_si: Switch to use platform_get_mem_or_io()
ipmi_si: Remove bogus err_free label
ipmi_si: Utilize temporary variable to hold device pointer
ipmi_si: Use proper ACPI macros to check error code for failures
ipmi_si: Introduce ipmi_panic_event_str[] array
ipmi_si: Reuse si_to_str[] array in ipmi_hardcode_init_one()
ipmi_si: Get rid of ->addr_source_cleanup()
ipmi_si: Use strstrip() to remove surrounding spaces
ipmi_si: Drop redundant check before calling put_device()
ipmi_si: Join string literals back
