Error building RT2860 WLAN driver in kernel 2.6.18-128.2.1.4.25.el5.i686

Question

Hello,
I installed VM Server v2.2.1 (kernel 2.6.18-128.2.1.4.25.el5.i686) and am trying to build the RT2860 WLAN driver from source (2010_07_16_RT2860_Linux_STA_v2.4.0.0). I installed package kernel-ovs-devel-2.6.18-128.2.1.4.25.el5.i686 and when I run make I get the following compile error:
error: expected identifier or '(' before 'void'
The offending snippet of code, from a header file, is:
typedef VOID (*STATE_MACHINE_FUNC)(VOID Adaptor, MLME_QUEUE_ELEM Elem);
typedef struct STATEMACHINE {
ULONG Base;
ULONG NrState;
ULONG NrMsg;
ULONG CurrState;
STATE_MACHINE_FUNC *TransFunc;
} STATE_MACHINE, *PSTATE_MACHINE;
The odd thing is, I'm able to build the source when I replace kernel-ovs-devel-2.6.18-128.2.1.4.25.el5.i686 with kernel-devel-2.6.18-128.2.1.4.25.el5.i686 or with kernel-xen-devel-2.6.18-128.2.1.el5.i686 but then, of course, I get an "Invalid module format" error when I try to install the module (/sbin/insmod rt2860sta.ko).
The issue is probably very simple to solve, but I'm not much of a C programmer so it's not clear to me why the compiler is choking on the snippet above.
Thanks in advance for any advice,
Matt

This issue has been resolved. The problem was, we were (attempting to) use EMC PowerPath (/dev/emcpower* devices) but the default SCSI devices (/dev/sd*) were being discovered and used as path to storage.
The solution was to edit /etc/sysconfig/oracleasm and add "emcpower" to the ORACLEASM_SCANORDER parameter and "sd" to the ORACLEASM_SCANEXCLUDE parameter. Once we did that, failovers are working successfully.
