add Fujitsu Lifebook E546 to force crc_enabled

Hi,

I have seen this messages https://patchwork.kernel.org/patch/9645671/
about adding Fujitsu Lifebook E547 to force crc_enabled.
I own Fujitsu Lifebook E546 and I have the same problem, I currently
force crc_enabled through rc.local, but I think it should also be
included in the kernel.

Regards,
Dimitar
