[PATCHv2] qla2xxx: Correct compilation issues whenCONFIG_MOUDLES=n.

From: Andrew Vasquez
Date: Fri Sep 11 2009 - 20:38:26 EST


Randy Dunlap noted:

when CONFIG_MODULES=n:

drivers/scsi/qla2xxx/qla_os.c:2685: error: dereferencing pointer to incomplete type

in

kobject_uevent_env(&(&vha->hw->pdev->driver->driver)->owner->mkobj.kobj,
KOBJ_CHANGE, envp);

Trigger kobject event on the 'struct device' hanging off the pci_dev.

Ok, with the kobject_uevent_env() change and the udev-rule modified to:

SUBSYSTEM=="pci", ENV{DRIVER}="qla2xxx", ACTION=="change", RUN+="qla2xxx_udev.sh"

we're working again.

This seem reasonable?

Thanks, AV
