Hello, this is the final patch set for my effort to make struct bus_type::remove return void. The first four patches contain cleanups that make some of these callbacks (more obviously) always return 0. They are acked by the respective maintainers. Bjorn Helgaas explicitly asked to include the pci patch (#1) into this series, so Greg taking this is fine. I assume the s390 people are fine with Greg taking patches #2 to #4, too, they didn't explicitly said so though. The last patch actually changes the prototype and so touches quite some drivers and has the potential to conflict with future developments, so I consider it beneficial to put these patches into next soon. I expect that it will be Greg who takes the complete series, he already confirmed via irc (for v2) to look into this series. In the last round I failed to send the cover letter to all affected people, sorry for that, this should be fixed now. Best regards Uwe Changes since v2: - Add several acks/review tags - Include patch #1 explicitly - rebase to v5.14-rc1, build test on amd64, arm64 and s390 using allmodconfig Uwe Kleine-König (5): PCI: endpoint: Make struct pci_epf_driver::remove return void s390/cio: Make struct css_driver::remove return void s390/ccwgroup: Drop if with an always false condition s390/scm: Make struct scm_driver::remove return void bus: Make remove callback return void arch/arm/common/locomo.c | 3 +-- arch/arm/common/sa1111.c | 4 +--- arch/arm/mach-rpc/ecard.c | 4 +--- arch/mips/sgi-ip22/ip22-gio.c | 3 +-- arch/parisc/kernel/drivers.c | 5 ++--- arch/powerpc/platforms/ps3/system-bus.c | 3 +-- arch/powerpc/platforms/pseries/ibmebus.c | 3 +-- arch/powerpc/platforms/pseries/vio.c | 3 +-- arch/s390/include/asm/eadm.h | 2 +- drivers/acpi/bus.c | 3 +-- drivers/amba/bus.c | 4 +--- drivers/base/auxiliary.c | 4 +--- drivers/base/isa.c | 4 +--- drivers/base/platform.c | 4 +--- drivers/bcma/main.c | 6 ++---- drivers/bus/sunxi-rsb.c | 4 +--- drivers/cxl/core.c | 3 +-- drivers/dax/bus.c | 4 +--- drivers/dma/idxd/sysfs.c | 4 +--- drivers/firewire/core-device.c | 4 +--- drivers/firmware/arm_scmi/bus.c | 4 +--- drivers/firmware/google/coreboot_table.c | 4 +--- drivers/fpga/dfl.c | 4 +--- drivers/hid/hid-core.c | 4 +--- drivers/hid/intel-ish-hid/ishtp/bus.c | 4 +--- drivers/hv/vmbus_drv.c | 5 +---- drivers/hwtracing/intel_th/core.c | 4 +--- drivers/i2c/i2c-core-base.c | 5 +---- drivers/i3c/master.c | 4 +--- drivers/input/gameport/gameport.c | 3 +-- drivers/input/serio/serio.c | 3 +-- drivers/ipack/ipack.c | 4 +--- drivers/macintosh/macio_asic.c | 4 +--- drivers/mcb/mcb-core.c | 4 +--- drivers/media/pci/bt8xx/bttv-gpio.c | 3 +-- drivers/memstick/core/memstick.c | 3 +-- drivers/mfd/mcp-core.c | 3 +-- drivers/misc/mei/bus.c | 4 +--- drivers/misc/tifm_core.c | 3 +-- drivers/mmc/core/bus.c | 4 +--- drivers/mmc/core/sdio_bus.c | 4 +--- drivers/net/netdevsim/bus.c | 3 +-- drivers/ntb/core.c | 4 +--- drivers/ntb/ntb_transport.c | 4 +--- drivers/nvdimm/bus.c | 3 +-- drivers/pci/endpoint/pci-epf-core.c | 7 ++----- drivers/pci/pci-driver.c | 3 +-- drivers/pcmcia/ds.c | 4 +--- drivers/platform/surface/aggregator/bus.c | 4 +--- drivers/platform/x86/wmi.c | 4 +--- drivers/pnp/driver.c | 3 +-- drivers/rapidio/rio-driver.c | 4 +--- drivers/rpmsg/rpmsg_core.c | 7 ++----- drivers/s390/block/scm_drv.c | 4 +--- drivers/s390/cio/ccwgroup.c | 6 +----- drivers/s390/cio/chsc_sch.c | 3 +-- drivers/s390/cio/css.c | 7 +++---- drivers/s390/cio/css.h | 2 +- drivers/s390/cio/device.c | 9 +++------ drivers/s390/cio/eadm_sch.c | 4 +--- drivers/s390/cio/scm.c | 5 +++-- drivers/s390/cio/vfio_ccw_drv.c | 3 +-- drivers/s390/crypto/ap_bus.c | 4 +--- drivers/scsi/scsi_debug.c | 3 +-- drivers/siox/siox-core.c | 4 +--- drivers/slimbus/core.c | 4 +--- drivers/soc/qcom/apr.c | 4 +--- drivers/spi/spi.c | 4 +--- drivers/spmi/spmi.c | 3 +-- drivers/ssb/main.c | 4 +--- drivers/staging/fieldbus/anybuss/host.c | 4 +--- drivers/staging/greybus/gbphy.c | 4 +--- drivers/target/loopback/tcm_loop.c | 5 ++--- drivers/thunderbolt/domain.c | 4 +--- drivers/tty/serdev/core.c | 4 +--- drivers/usb/common/ulpi.c | 4 +--- drivers/usb/serial/bus.c | 4 +--- drivers/usb/typec/bus.c | 4 +--- drivers/vdpa/vdpa.c | 4 +--- drivers/vfio/mdev/mdev_driver.c | 4 +--- drivers/virtio/virtio.c | 3 +-- drivers/vme/vme.c | 4 +--- drivers/xen/xenbus/xenbus.h | 2 +- drivers/xen/xenbus/xenbus_probe.c | 4 +--- include/linux/device/bus.h | 2 +- include/linux/pci-epf.h | 2 +- sound/aoa/soundbus/core.c | 4 +--- 87 files changed, 98 insertions(+), 241 deletions(-) base-commit: e73f0f0ee7541171d89f2e2491130c7771ba58d3 -- 2.30.2
