Kconfig dangling references (BZ 216748)

Kconfig dangling references (BZ 216748)

[Randy Dunlap]

from  https://bugzilla.kernel.org/show_bug.cgi?id=216748

The bugzilla entry includes a Perl script and a shell script.
This is the edited result of running them (I removed some entries that were noise).

I'll try to Cc: all of the relevant mailing lists or individuals.

Thanks Randy! This is good.

This is a config for stuff that never went upstream. It was replaced by 
more sophisticated kunit_device, which I believe is behind the 
'CONFIG_KUNIT'. So, this should be dropped, thanks!

My mistake, this was a botched rebase.

This apparently never made it upstream because it was unreliable

This was likely intended for 32-bit kernels on 64-bit STM32MP25
chips, which we don't support. I think this can go.

I don't think we'll merge the rest of Baikal, we should probably
remove the entire platform.

Should have been removed as part of 7518f0763ecd ("sh: convert
boards to use the OHCI platform driver")

I missed this in f388f60ca904 ("x86/cpu: Drop configuration options
for early 64-bit CPUs"). Both references can be removed, because
p6-nop was already disallowed for 32-bit CPUs at the time.

I don't know if any supported binutils still require -mtune=generic32

Max is still working on esp32 support as far as I know, it's just
slow progress, see

This must be a bogus entry added in commit 1c8bc7b3de5e ("ASoC: pxa:
switch to new ac97 bus support"), which can be dropped.

The buggy commit was 32172cf3cb54 ("ASoC: cs35l56: Allow restoring
factory calibration through ALSA control").
This looks like a fallout at changing from sysfs to debugfs, so this
should be SND_SOC_CS35L56_CAL_DEBUGFS_COMMON instead.

Yes, I fully agree!

I have a series pinctrl stm32 to be rebased on v6.19-rc1 and I can include the
drop of MACH_STM32MP25 inside it.

For these two, the symbol was removed in commit
09717af7d13d63df141ae6e71686289989d17efd but these two drivers either were
missed by the batch rename or were introduced a bit later.

Since the symbol selected DRM_GEM_CMA_HELPER (which is still needed by the
drivers), it should be replaced with DRM_GEM_CMA_HELPER.

Are you expecting to craft a patch for fixing this or should I do it myself?

All the best,

Paul

That commit removed DRM_KMS_CMA_HELPER. Later commit 6bcfe8eaeef0
("drm/fb: rename FB CMA helpers to FB DMA helpers") renamed
DRM_KMS_CMA_HELPER erroneously to DRM_KMS_DMA_HELPER.

In the case of drivers/gpu/drm/adp/Kconfig it was missed much later
during review (but iirc went through the same rename out of tree).

That symbol doesn't exist anymore either. It's now DRM_GEM_DMA_HELPER
which is already present in both files.

So the "select DRM_KMS_DMA_HELPER" lines can be removed from both files.

Oh! I checked multiple times that I'd changed all the sysfs to debugfs
and this STILL got through. I'll send a fix.

Those were added when upstreaming support for the JZ4755/JZ4760, but
the DTS files and actual support in arch/mips/ was never sent.

Instead of dropping those, I'll try to upstream the basic support for
those SoCs in the coming days.
