79f237ba - ACPI: bus: change the prototype for acpi_get_physical_device_location

Mon, 16 Dec 2024 21:17:15 +0000

ACPI: bus: change the prototype for acpi_get_physical_device_locationIt generally is not OK to use acpi_status and/or AE_ error codeswithout CONFIG_ACPI and they really only should be used indrivers/acpi/ (and not everywhere in there for that matter).So acpi_get_physical_device_location() needs to be redefined to returnsomething different from acpi_status (preferably bool) in order to beused in !CONFIG_ACPI code.Suggested-by: Rafael J.

0d150f96 - driver core: location: Free struct acpi_pld_info *pld before return false

driver core: location: Free struct acpi_pld_info *pld before return falsestruct acpi_pld_info *pld should be freed before the return of allocationfailure, to prevent memory leak, add the ACPI_FREE() to fix it.Fixes: bc443c31def5 ("driver core: location: Check for allocations failure")Signed-off-by: Hanjun Guo Link: https://lore.kernel.org/r/1669102648-11517-1-git-send-email-guohanjun@huawei.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/base/physical_location.c

6423d295 - driver core: Add sysfs support for physical location of a device

Mon, 14 Mar 2022 19:54:58 +0000

driver core: Add sysfs support for physical location of a deviceWhen ACPI table includes _PLD fields for a device, create a newdirectory (physical_location) in sysfs to share _PLD fields.Currently without PLD information, when there are multiple of samedevices, it is hard to distinguish which device corresponds to whichphysical device at which location. For example, when there are two TypeC connectors, it is hard to find out which connector corresponds to theType C port on the left panel versus the Type C port on the right panel.With PLD information provided, we can determine which specific device atwhich location is doing what._PLD output includes much more fields, but only generic fields are addedand exposed to sysfs, so that non-ACPI devices can also support it inthe future. The minimal generic fields needed for locating a device arethe following.- panel- vertical_position- horizontal_position- dock- lidSigned-off-by: Won Chung Link: https://lore.kernel.org/r/20220314195458.271430-1-wonchung@google.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/base/physical_location.c
