Subject: platform/x86: Replace acpi_bus_get_device()
Patch-mainline: v5.18-rc1
Git-commit: f7e62c5890f08543e7b4d305c4b4501f89aafe61
References: jsc#PED-1408
Replace acpi_bus_get_device() that is going to be dropped with
acpi_fetch_acpi_dev().
No intentional functional impact.
Joey Lee:
- Only applied thinkpad_acpi.c parts because other drivers are
not supported in SLE15-SP5.
