I sent a patch on March 09, 2010, that should fix it.
Please test it.  Thanks.

From: Randy Dunlap <randy.dunlap@...cle.com>

When the dt3155 driver is built-in (not as a loadable module),
these build errors happen:

drivers/staging/dt3155/dt3155_drv.c:1047: error: implicit declaration of function 'request_irq'
drivers/staging/dt3155/dt3155_drv.c:1048: error: 'IRQF_SHARED' undeclared (first use in this function)
drivers/staging/dt3155/dt3155_drv.c:1048: error: 'IRQF_DISABLED' undeclared (first use in this function)
drivers/staging/dt3155/dt3155_drv.c:1091: error: implicit declaration of function 'free_irq'

so remove the #ifdef MODULE check since it's not needed.
Also remove the CONFIG_PCI check since the Kconfig file already
requires that.
