2023-03-23usb: phy: ab8500: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-03-23xhci: Avoid PCI MSI/MSIX interrupt reinitialization at resumeJosue David Hernandez Gutierrez3-6/+18
xhci MSI setup is currently done at the same time as xHC host is started in xhci_run(). This couples the generic xhci code with PCI, and will reconfigure MSI/MSIX interrupts every time xHC is started. Decouple MSI/MSIX configuration from generic xhci code by moving MSI/MSIX part to a PCI specific xhci_pci_run() function overriding xhci_run(). This allows us to remove unnecessay MSI/MSIX reconfiguration done every time PCI xhci resumes from suspend. i.e. remove the xhci_cleanup_msix() call from xhci_resume() and the xhci_try_enale_msi() call in xhci_run() called a bit later by xhci_resume() [minor changes and commit message rewrite -Mathias] Signed-off-by: Josue David Hernandez Gutierrez <[email protected]> Signed-off-by: Mathias Nyman <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>

Most of the values are hardcoded, but some fields such as idProduct, idVendor, bcdDevice and bInterfaceProtocol can be modified. Add sysfs entries that allow userspace to change these. User can only change them before dbc is enabled, i.e. before writing "enable" to dbc sysfs file as we don't want these values to change while device is connected, or during enumeration.

This driver didn't see real maintainance since several years. It has several trivial issues (check $(scripts/checkpatch.pl -f drivers/usb/misc/ftdi-elan.c)) and some harder ones (difficult locking, explict kref handling, ...). Also today it's hard to find hardware to make actually use of such a card and I suspect the driver is completely unused. So remove it.

This driver got its last actual change in 2006 and is probably unused as nowbody should use a cardbus to USB adapter any more. If it were still used, the driver was in urgent need for maintainer love. (Explicit kref handling, underdocumented locking, .remove() can return errors ...) Also the link in the (now removed) help text doesn't look actively maintained. According to archive.org it forwarded to http://www.copenhagen-hotel.net/ already back in 2018. So don't waste more time on this driver and just delete it.

2023-03-17wwan: core: Support slicing in port TX flow of WWAN subsystemhaozhe chang1-1/+2
wwan_port_fops_write inputs the SKB parameter to the TX callback of the WWAN device driver. However, the WWAN device (e.g., t7xx) may have an MTU less than the size of SKB, causing the TX buffer to be sliced and copied once more in the WWAN device driver. This patch implements the slicing in the WWAN subsystem and gives the WWAN devices driver the option to slice(by frag_len) or not. By doing so, the additional memory copy is reduced. Meanwhile, this patch gives WWAN devices driver the option to reserve headroom in fragments for the device-specific metadata.

2023-03-16usb: acpi: Switch to use acpi_evaluate_dsm_typed()Andy Shevchenko1-8/+4
The acpi_evaluate_dsm_typed() provides a way to check the type of the object evaluated by _DSM call. Use it instead of open coded variant. Signed-off-by: Andy Shevchenko <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2023-03-16usb: Use of_property_read_bool() for boolean propertiesRob Herring6-32/+25
It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. Convert reading boolean properties to to of_property_read_bool().

2023-03-16usb: Use of_property_present() for testing DT property presenceRob Herring5-6/+6
It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.
