Hi Stephen,
Problem is in Makefile:
obj-$(CONFIG_BLK_DEV_SR) += cdrom.o
obj-$(CONFIG_PARIDE_PCD) += cdrom.o
obj-$(CONFIG_CDROM_PKTCDVD) += cdrom.o
+obj-$(CONFIG_SYSCTL) += cdrom_sysctl.o
I tried cdrom-$(CONFIG_SYSCTL) += cdrom_sysctl.o
to add sysctl only when cdrom.o is created
but now
drivers/scsi/sr_mod.ko
drivers/ide/ide-cd_mod.ko
drivers/ide/ide-cd_mod.ko
can't find cdrom.c functions ...
Is there another way to do it ?
Regards,
Fabian
