Re: [PATCH 02/15] ATA : vortex86 : fix vortex86dx/sx hardware CRC bug.

Thanks, That was a good catch.  I had that extra struct for another
revision of the RDC peripheral integrated into the
Vortex86DX.  I removed it when I moved it to the pata_rdc.c driver but
forgot the struct.  The it821x driver works
for the RDC drivers when DMA is turned off.  But the RDC driver is the
more logical choice.

I will make the fix and send out the new patch.

I accidentally sent this through the gmail interface with html on,
Some of you may get this email twice.

Thanks,
Paul Schilling
