[PATCH 1/3] ssb: PCI revision ID register is 8-bit wide
From: Sergei Shtylyov <hidden>
Date: 2011-07-01 18:33:49
The SSB code reads PCI revision ID register as 16-bit entity while the register is actually 8-bit only (the next 8 bits are the programming interface register). Fix the read and make the 'rev' field of 'struct ssb_boardinfo' 8-bit as well, to match the register size.
