[PATCH v4 02/19] ACPI: platform_profile: Let drivers set drvdata to the class device

Kurt Borja
2025-01-16T00:27:49Z

Add *drvdata to platform_profile_register() signature and assign it to
the class device.

While at it, pass specific driver state as drvdata to replace uses of
container_of() with dev_get_drvdata().
