CONFIG_FORTIFY_SOURCE causes amdgpu to fail compilation

amdgpu driver (DC part) fails compilation when compiling with CONFIG_FORTIFY_SOURCE option:

In function ‘memmove’,
    inlined from ‘append_entry’ at drivers/gpu/drm/amd/amdgpu/../display/dc/basics/logger.c:258:2,
    inlined from ‘dm_logger_append_va.part.5’ at drivers/gpu/drm/amd/amdgpu/../display/dc/basics/logger.c:349:4:
./include/linux/string.h:356:4: error: call to ‘__read_overflow2’ declared with attribute error: detected read beyond size of object passed as 2nd parameter
    __read_overflow2();
    ^~~~~~~~~~~~~~~~~~

I have attached a patch which resolves this problem.
