When CONFIG_DT3155=y (i.e., not a loadable module):

(a)
drivers/staging/dt3155/dt3155_drv.c:967: error: implicit declaration of function 'pci_find_device'
drivers/staging/dt3155/dt3155_drv.c:1151: error: implicit declaration of function 'request_irq'
drivers/staging/dt3155/dt3155_drv.c:1152: error: 'IRQF_SHARED' undeclared (first use in this function)
drivers/staging/dt3155/dt3155_drv.c:1152: error: 'IRQF_DISABLED' undeclared (first use in this function)
drivers/staging/dt3155/dt3155_drv.c:1195: error: implicit declaration of function 'free_irq'


#ifdef MODULE
#include <linux/interrupt.h>

linux/interrupt.h is needed for DT3155=y, not just when DT3155=m.

Oh, and this config has:  # CONFIG_PCI_LEGACY is not set
which accounts for pci_find_device() being unknown.
If that is required (as it is currently, even though this function is
deprecated), it can be expressed in the driver's Kconfig file:
	depends on PCI_LEGACY



(b) when compiling goes further:

drivers/staging/dt3155/dt3155_drv.c:571: warning: format '%x' expects type 'unsigned int', but argument 2 has type 'long unsigned int'
drivers/staging/dt3155/dt3155_drv.c:571: warning: format '%x' expects type 'unsigned int', but argument 3 has type 'long unsigned int'
drivers/staging/dt3155/dt3155_drv.c:657: warning: format '%x' expects type 'unsigned int', but argument 2 has type 'long unsigned int'
drivers/staging/dt3155/dt3155_drv.c:657: warning: format '%x' expects type 'unsigned int', but argument 3 has type 'long unsigned int'



General:

#ifndef CONFIG_PCI
#error  "DT3155 :  Kernel PCI support not enabled (DT3155 drive requires PCI)"
#endif

That should be handled via Kconfig, not in a .c file.
Ah, it is done in Kconfig, so those lines above (in .c file) can be deleted.
