From 132565d8ec096a5a043f96092cfa4821d970d268 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 7 May 2020 12:49:16 +0200 Subject: ACPI: utils: Add acpi_evaluate_reg() helper With a recent fix to the pinctrl-cherryview driver we now have 2 drivers open-coding the parameter building / passing for calling _REG on an ACPI handle. Add a helper for this, so that these 2 drivers can be converted to this helper. Suggested-by: Andy Shevchenko Reviewed-by: Andy Shevchenko Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
