dead CONFIG variables in kernel Makefiles

dead CONFIG variables in kernel Makefiles

[Robert P. J. Day]

  the output from a short script i wrote, locating all CONFIG_
variables in makefiles that don't appear to exist in any Kconfig file
anywhere in the source tree.

  first, from the drivers/ directory:

===== DRM_FFB =====
./drivers/char/drm/Makefile:obj-$(CONFIG_DRM_FFB)   += ffb.o
===== INPUT_POWER =====
./drivers/input/Makefile:obj-$(CONFIG_INPUT_POWER)      += power.o
===== IPATH_CORE =====
./drivers/Makefile:obj-$(CONFIG_IPATH_CORE)     += infiniband/
===== L7200_KEYB =====
./drivers/acorn/char/Makefile:obj-$(CONFIG_L7200_KEYB)  += defkeymap-l7200.o keyb_l7200.o
===== RADIO_MIROPCM20 =====
./drivers/media/radio/Makefile:obj-$(CONFIG_RADIO_MIROPCM20) += miropcm20.o
===== RADIO_MIROPCM20_RDS =====
./drivers/media/radio/Makefile:obj-$(CONFIG_RADIO_MIROPCM20_RDS) += miropcm20-rds.o
===== SCSI_FD_8xx =====
./drivers/scsi/Makefile:obj-$(CONFIG_SCSI_FD_8xx)       += seagate.o
===== USB_EGALAX =====
./drivers/usb/input/Makefile:obj-$(CONFIG_USB_EGALAX)   += touchkitusb.o
===== USB_ITMTOUCH =====
./drivers/usb/input/Makefile:obj-$(CONFIG_USB_ITMTOUCH) += itmtouch.o
===== USB_MTOUCH =====
./drivers/usb/Makefile:obj-$(CONFIG_USB_MTOUCH) += input/
./drivers/usb/input/Makefile:obj-$(CONFIG_USB_MTOUCH)   += mtouchusb.o
===== USB_OHCI_AT91 =====
./drivers/usb/Makefile:obj-$(CONFIG_USB_OHCI_AT91)      += host/
===== ZS =====
./drivers/tc/Makefile:obj-$(CONFIG_ZS) += zs.o

  and from the fs/ directory:

===== NLS_ABC =====
./fs/nls/Makefile:obj-$(CONFIG_NLS_ABC)         += nls_abc.o
===== NLS_ISO8859_10 =====
./fs/nls/Makefile:obj-$(CONFIG_NLS_ISO8859_10)  += nls_iso8859-10.o

Thanks, I was just noticing that myself.  I'll remove it for 2.6.22.

I'll take care of this one, thanks Robert.

Part of an OSS driver removal, patch for 2.6.22 already submitted.

Ralf, is there any reason why the code for this driver is in Linus' 
tree, but the option (that is in the mips tree) is missing?

that's because we couldnt push the rest of the BF54x port until the
new merge window ... they'll be defined with 2.6.23

> ===== CPU_FREQ_BF533 =====

we changed names in the Kconfig but didnt sync that Makefile ... the
others got updated
