From: Larry Finger Date: Mon, 9 Nov 2009 16:53:20 +0000 (-0600) Subject: Staging: rtl8187se: Remove card8185 variable to simplify flow X-Git-Tag: MMI-PSA29.97-13-9~25324^2~50 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d44eb889ccf80e417794963e57cc40bd1519e554;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git Staging: rtl8187se: Remove card8185 variable to simplify flow When this code is used for the rtl8187se, the value of card_8185 in struct r8180_priv is always 7 or 8. As a result, the program flow can be simplified.
