Commit Message

Instead of "open coding" DEVICE_ATTR, use the corresponding
helper macros DEVICE_ATTR_{RW,RO,WO} in amd64_edac.c

Some function names needed to be changed to match the device
conventions <foo>_show and <foo>_store, but the functionality
itself is unchanged.

The devices using EDAC_DCT_ATTR_SHOW() are left unchanged.

Changes in v3:
- Reword patch subject as suggested by Yazen and fix a typo.
  https://lore.kernel.org/lkml/20210712194433.GA1002@aus-x-yghannam.amd.com/

Changes in v2:
- Revert back the device name changes which broke
  the kernel. These were using the macro EDAC_DCT_ATTR_SHOW()
  to construct the show methods based on device name.
  Reported by Kernel test bot.

Yazen,

Boris is on vacation. Should I queue this change?
