2024-04-04Bluetooth: btmrvl_sdio: drop driver owner initializationKrzysztof Kozlowski
Core in sdio_register_driver() already sets the .owner, so driver does not need to. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20240403-module-owner-sdio-v2-1-ae46d6b955eb@linaro.org Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

2024-04-02mmc: sdio: store owner from modules with sdio_register_driver()Krzysztof Kozlowski
Modules registering driver with sdio_register_driver() might forget to set .owner field. The field is used by some of other kernel parts for reference counting (try_module_get()), so it is expected that drivers will set it. Solve the problem by moving this task away from the drivers to the core code, just like we did for platform_driver in commit 9447057eaff8 ("platform_device: use a macro instead of platform_driver_register"). Since many drivers forget to set the .owner, this effectively will fix them. Examples of fixed drivers are: ath6kl, b43, btsdio.c, ks7010, libertas, MediaTek WiFi drivers, Realtek WiFi drivers, rsi, siano, wilc1000, wl1251 and more.

2024-04-02mmc: sdhci-pci-gli: Use pci_set_power_state(), not direct PMCSR writesBjorn Helgaas
d7133797e9e1 ("mmc: sdhci-pci-gli: A workaround to allow GL9750 to enter ASPM L1.2") and 36ed2fd32b2c ("mmc: sdhci-pci-gli: A workaround to allow GL9755 to enter ASPM L1.2") added writes to the Control register in the Power Management Capability to put the device in D3hot and back to D0. Use the pci_set_power_state() interface instead because these are generic operations that don't need to be driver-specific. Also, the PCI spec requires some delays after these power transitions, and pci_set_power_state() takes care of those, while d7133797e9e1 and 36ed2fd32b2c did not.

2024-04-02mmc: sdhci-pci-gli: Use PCI AER definitions, not hard-coded valuesBjorn Helgaas
015c9cbcf0ad ("mmc: sdhci-pci-gli: GL9750: Mask the replay timer timeout of AER") added PCI_GLI_9750_CORRERR_MASK, the offset of the AER Capability in config space, and PCI_GLI_9750_CORRERR_MASK_REPLAY_TIMER_TIMEOUT, the Replay Timer Timeout bit in the AER Correctable Error Status register. Use pci_find_ext_capability() to locate the AER Capability and use the existing PCI_ERR_COR_REP_TIMER definition to mask the bit. This removes a little bit of unnecessarily device-specific code and makes AER-related things more greppable.

2024-04-02mmc: davinci: Don't strip remove function when driver is builtinUwe Kleine-König
Using __exit for the remove function results in the remove callback being discarded with CONFIG_MMC_DAVINCI=y. When such a device gets unbound (e.g. using sysfs or hotplug), the driver is just removed without the cleanup being performed. This results in resource leaks. Fix it by compiling in the remove callback unconditionally. This also fixes a W=1 modpost warning: WARNING: modpost: drivers/mmc/host/davinci_mmc: section mismatch in reference: davinci_mmcsd_driver+0x10 (section: .data) -> davinci_mmcsd_remove (section: .exit.text) Fixes: b4cff4549b7a ("DaVinci: MMC: MMC/SD controller driver for DaVinci family") Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20240324114017.231936-2-u.kleine-koenig@pengutronix.de Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

It seems the of_get_named_gpio() is solely used to check if the GPIO is present in DT as the function can return 0 if and only if it's present and it becomes in the global number space 0. But this quite likely shows that the code wasn't ever been tested on the systems when no GPIO is provided. In any case, the proper test is just to call of_property_present() without any attempts in requesting GPIO (as we haven't saved the number or descriptor anywhere in the code).

2024-03-31kbuild: Disable KCSAN for autogenerated *.mod.c intermediariesBorislav Petkov (AMD)
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.

2024-03-31kbuild: make -Woverride-init warnings more consistentArnd Bergmann
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.

The enhancements for lpfc are log message removals, copyright updates and three patches redefining types. For qla2xxx it's just removing a debug message on module removal and the manufacturer detail update.

2024-03-30x86/build: Use obj-y to descend into arch/x86/virt/Masahiro Yamada
Commit c33621b4c5ad ("x86/virt/tdx: Wire up basic SEAMCALL functions") introduced a new instance of core-y instead of the standardized obj-y syntax. X86 Makefiles descend into subdirectories of arch/x86/virt inconsistently; into arch/x86/virt/ via core-y defined in arch/x86/Makefile, but into arch/x86/virt/svm/ via obj-y defined in arch/x86/Kbuild. This is problematic when you build a single object in parallel because multiple threads attempt to build the same file. $ make -j$(nproc) arch/x86/virt/vmx/tdx/seamcall.o [ snip ] AS arch/x86/virt/vmx/tdx/seamcall.o AS arch/x86/virt/vmx/tdx/seamcall.o fixdep: error opening file: arch/x86/virt/vmx/tdx/.seamcall.o.d: No such file or directory make[4]: *** [scripts/Makefile.build:362: arch/x86/virt/vmx/tdx/seamcall.o] Error 2 Use the obj-y syntax, as it works correctly.
