X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=814c978f02db17f16e6aa2efa2a929372f06da09;p=linux.git

nvmem: Add macro to register nvmem layout drivers

Provide a module_nvmem_layout_driver() macro at the end of the
nvmem-provider.h header to reduce the boilerplate when registering nvmem
layout drivers.
