No, however you can define module variables which will be passed to the driver.
Example (for 2.2.x):
/* Module parameters */
int unacceptable_mask = 0; /* You can use this to bypass detection
* of the boards. E.g. setting to 4
* will skip the 3rd board.
*/
#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,2,0)
MODULE_PARM(unacceptable_mask, "i");
#endif /* >= 2.2.0 */
Use:
insmod driver.o unacceptable_mask=1
Used in conjunction with on-demand loading (/etc/conf.modules) or with
startup scripts, you get mostly similar functionnality.
