From: Gertjan van Wingerde Date: Sat, 13 Feb 2010 19:55:48 +0000 (+0100) Subject: rt2x00: Reorganize RT chipset setting for PCI/SOC devices. X-Git-Tag: MMI-PSA29.97-13-9~24841^2~49^2~57 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=714fa6636331d33c6045efe394f36c964a6c14ee;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git rt2x00: Reorganize RT chipset setting for PCI/SOC devices. Don't set the RT chipset for a device from within the generic PCI/SOC code, but rather from the individual drivers, so that individual drivers have more control over what RT chipset is set. Preparation for chip handling updates for rt2800 devices. Signed-off-by: Gertjan van Wingerde Acked-by: Ivo van Doorn Signed-off-by: John W.
