| |
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.
