Merge branch 'acpi-uid'
Merge ACPI _UID handling unification changes for 6.1-rc1:
- Introduce acpi_dev_uid_to_integer() to convert a _UID string into an
integer value (Andy Shevchenko).
- Use acpi_dev_uid_to_integer() in several places to unify _UID
handling (Andy Shevchenko).
* acpi-uid:
efi/dev-path-parser: Refactor _UID handling to use acpi_dev_uid_to_integer()
spi: pxa2xx: Refactor _UID handling to use acpi_dev_uid_to_integer()
perf: qcom_l2_pmu: Refactor _UID handling to use acpi_dev_uid_to_integer()
i2c: mlxbf: Refactor _UID handling to use acpi_dev_uid_to_integer()
i2c: amd-mp2-plat: Refactor _UID handling to use acpi_dev_uid_to_integer()
ACPI: x86: Refactor _UID handling to use acpi_dev_uid_to_integer()
ACPI: LPSS: Refactor _UID handling to use acpi_dev_uid_to_integer()
ACPI: utils: Add acpi_dev_uid_to_integer() helper to get _UID as integer
