Sergei,
Thanks, I will take care of and have a question about style

	 portsc = ioread32(ci->hw_bank.regmap[OP_PORTSC] & PORTSC_STS;

the line in the if/else alignment extent the 80char barrier and should be 
splitted in this case '&' is at 81 .. how serious I should follow this one?

  	 portsc = ioread32(ci->hw_bank.regmap[OP_PORTSC] &
                     PORTSC_STS;

I keep this mail private don't want make too much noise on the list.

regards
Chris
