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. Reviewed-by: Yazen Ghannam <yazen.ghannam(a)amd.com&gt; Signed-off-by: Dwaipayan Ray <dwaipayanray1(a)gmail.com&gt; --- 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.
