The incompatible device in my possession has a sticker that says "F5U002 Rev 2" and "P80453-B", and lsusb identifies it as "050d:0002 Belkin Components IEEE-1284 Controller". There is a bug report from 2007 from Michael Trausch who was seeing the exact same errors that I saw in 2024 trying to use this cable.

This device is a gray USB parallel port adapter with "F5U002" imprinted on the plastic and a sticker that says both "F5U002" and "P80453-A". It's identified in lsusb as "05ab:1001 In-System Design BAYI Printer Class Support". It's subtly different from the other gray cable I have that has "F5U002 Rev 2" and "P80453-B" on its sticker and device ID 050d:0002. The uss720 driver appears to work flawlessly with this device, although the device evidently does not support ECP. Signed-off-by:

Some PPM implementation do not like UCSI_ACK_CONNECTOR_CHANGE without UCSI_ACK_COMMAND_COMPLETE. Moreover, doing this is racy as it requires sending two UCSI_ACK_CC_CI commands in a row and the second one will be started with UCSI_CCI_ACK_COMPLETE already set in CCI. Bundle the UCSI_ACK_CONNECTOR_CHANGE with the UCSI_ACK_COMMAND_COMPLETE for the UCSI_GET_CONNECTOR_STATUS command that is sent while handling a connector change event. Signed-off-by:

In ucsi.h there are flag definitions for the ->flags field in struct ucsi. Some implementations abuse these bits for their private ->flags fields e.g. in struct ucsi_acpi. Move the definitions into the backend implementations that still need them. While there fix one instance where the flag name was not converted in a previous change. No semantic change intended.

Qualcomm firmware doesn't return sane information for device's PDOs unless the partner is also using a PD mode. On SC8280XP this even results in the Error bit being set in the UCSI response (with 0 error status).

In a way similar to the previous commit, move typec_partner_set_usb_power_delivery() to be called after reading the PD caps.

UCSI driver will attempt to set a USB PD device only if it was able to read PDOs from the firmware. This results in suboptimal behaviour, since the PD device will be created anyway.

CONFIG_DRM_AUX_BRIDGE depends on CONFIG_OF but that dependency is not included when CONFIG_TYPEC_MUX_PTN36502 selects it, resulting in a Kconfig warning when CONFIG_OF is disabled: WARNING: unmet direct dependencies detected for DRM_AUX_BRIDGE Depends on [n]: HAS_IOMEM [=y] && DRM_BRIDGE [=y] && OF [=n] Selected by [m]: - TYPEC_MUX_PTN36502 [=m] && USB_SUPPORT [=y] && TYPEC [=m] && I2C [=y] && (DRM [=y] || DRM [=y]=n) && DRM_BRIDGE [=y] Only select CONFIG_DRM_AUX_BRIDGE when CONFIG_DRM_BRIDGE and CONFIG_OF are enabled to clear up the warning.

As of the first s390 pull request during the 6.9 merge window, commit 691632f0 ("Merge tag 's390-6.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux"), s390 can be built with LLVM=1 when using LLVM 18.1.0, which is the first version that has SystemZ support implemented in ld.lld and llvm-objcopy. Update the supported architectures table in the Kbuild LLVM documentation to note this explicitly to make it more discoverable by users and other developers. Additionally, this brings s390 in line with the rest of the architectures in the table, which all support LLVM=1. Signed-off-by:

When KCSAN and CONSTRUCTORS are enabled, one can trigger the "Unpatched return thunk in use. This should not happen!" catch-all warning. Usually, when objtool runs on the .o objects, it does generate a section .return_sites which contains all offsets in the objects to the return thunks of the functions present there. Those return thunks then get patched at runtime by the alternatives. KCSAN and CONSTRUCTORS add this to the object file's .text.startup section: ------------------- Disassembly of section .text.startup: ... 0000000000000010 <_sub_I_00099_0>: 10: f3 0f 1e fa endbr64 14: e8 00 00 00 00 call 19 <_sub_I_00099_0+0x9> 15: R_X86_64_PLT32 __tsan_init-0x4 19: e9 00 00 00 00 jmp 1e <__UNIQUE_ID___addressable_cryptd_alloc_aead349+0x6> 1a: R_X86_64_PLT32 __x86_return_thunk-0x4 ------------------- which, if it is built as a module goes through the intermediary stage of creating a <module>.mod.c file which, when translated, receives a second constructor: ------------------- Disassembly of section .text.startup: 0000000000000010 <_sub_I_00099_0>: 10: f3 0f 1e fa endbr64 14: e8 00 00 00 00 call 19 <_sub_I_00099_0+0x9> 15: R_X86_64_PLT32 __tsan_init-0x4 19: e9 00 00 00 00 jmp 1e <_sub_I_00099_0+0xe> 1a: R_X86_64_PLT32 __x86_return_thunk-0x4 ... 0000000000000030 <_sub_I_00099_0>: 30: f3 0f 1e fa endbr64 34: e8 00 00 00 00 call 39 <_sub_I_00099_0+0x9> 35: R_X86_64_PLT32 __tsan_init-0x4 39: e9 00 00 00 00 jmp 3e <__ksymtab_cryptd_alloc_ahash+0x2> 3a: R_X86_64_PLT32 __x86_return_thunk-0x4 ------------------- in the .ko file. Objtool has run already so that second constructor's return thunk cannot be added to the .return_sites section and thus the return thunk remains unpatched and the warning rightfully fires. Drop KCSAN flags from the mod.c generation stage as those constructors do not contain data races one would be interested about.

The -Woverride-init warn about code that may be intentional or not, but the inintentional ones tend to be real bugs, so there is a bit of disagreement on whether this warning option should be enabled by default and we have multiple settings in scripts/Makefile.extrawarn as well as individual subsystems. Older versions of clang only supported -Wno-initializer-overrides with the same meaning as gcc's -Woverride-init, though all supported versions now work with both. Because of this difference, an earlier cleanup of mine accidentally turned the clang warning off for W=1 builds and only left it on for W=2, while it's still enabled for gcc with W=1. There is also one driver that only turns the warning off for newer versions of gcc but not other compilers, and some but not all the Makefiles still use a cc-disable-warning conditional that is no longer needed with supported compilers here. Address all of the above by removing the special cases for clang and always turning the warning off unconditionally where it got in the way, using the syntax that is supported by both compilers.
