[PATCH 1/7] EDAC, altera: New file operations for Arria10 ECC modules
From: tthayer at opensource.altera.com <hidden>

Subsystem:
arm/socfpga edac support, edac-core, the rest · Maintainers:
Dinh Nguyen, Borislav Petkov, Tony Luck, Linus Torvalds
From: Thor Thayer <redacted> In preparation for the Arria10 peripheral ECCs, new file operations are used because the Arria10 IRQ trigger mechanism is different than Cyclone5/Arria5 and Arria10 L2 cache. Add new pointer for file operations function to ecc data structure and point to current file operations function.
