Subject: Re: [PATCH 2/2] sp5100_tco: Write back the original value to reserved bits, instead of zero

Hi,

> In case of SP5100 or SB7x0 chipsets, the sp5100_tco module writes zero to
> reserved bits. The module, however, shouldn't depend on specific default
> value, and should perform a read-merge-write operation for the reserved
> bits.
> 
> This patch makes the sp5100_tco module perform a read-merge-write operation
> on all the chipset (sp5100, sb7x0, sb8x0 or later).
