From 304e21bbeab0d208dc7e6142fb75db8a466d5217 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Fri, 1 Jul 2011 22:35:28 +0400 Subject: ssb: PCI revision ID register is 8-bit wide 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. Signed-off-by: Sergei Shtylyov Signed-off-by: John W.
