You can keep a dead config option around for a while out of sympathy.
After a couple of releases it stops being "transitional" and starts
being "you are confusing every user who greps for it". These options
select nothing, gate nothing, and -- I checked by hand, this is not a
regex accident -- are referenced by exactly nobody in the tree.
Evidence for each removal:
* no CONFIG_<sym> reference outside the Kconfig definition itself
* no <sym> reference as an 'if'/'select'/'depends on' target
* no mention in any defconfig, any Documentation, or any source build
* the code they used to gate is gone (removed or folded into a real
driver that already has its own, functioning config symbol)
Headliners of the graveyard:
- HID_THINGM: help text literally said "will be removed soon". Well.
Gone now. The blink(1) driver is HJID_LED.
- USB_CONFIGFS_F_TCM: the real fabric always built via USB_F_TCM; the
"CONFIGFS" name was a leftover from when someone could not decide
what to call the thing.
- USB_EHCI_TEGRA, USB_OCTEON_OHCI, USB_OHCI_HCD_SSB: help text says
"driver was removed, use X instead". The other X already exists.
- PANEL: proudly labeled "OLD OPTION" with its own "Deprecated
options" section in the file. The actual parport lcd driver has
always been PARPORT_PANEL.
- COMMON_CLK_MT6765_*: seven sysclk entries with no matching object
in the Makefile. Zero files built, zero regrets.
- The usual kconfig-vandalism suspects (HAVE_PWRCTL, REGULATOR_MT6316,
INTERCONNECT_MTK_MT8196, CLK_SUNXI_PRCM_SUN9I, DVB_ULE_DEBUG, ...).
Validated: defconfig, olddefconfig and randconfig parse clean on both
x86_64 and arm64; headers_install (the target that replaced the dearly
departed headers_check, which this tree does not have) succeeds with a
clean UAPI on both architectures. Because someone will ask: yes, I
checked the s390/arm/riscv No, I did not delete any arch/* Kconfig, and
no, I did not touch a single include/uapi/ file.
Why should you care? Because "make menuconfig" allegedly lets people
configure the kernel, and leaving a menu full of options that do
nothing makes them feel like they have a choice when they really are
just being sold snake oil. Clean it up.
