From 3d7c821c1d8071e517048c8b4afdf33109441c0f Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 4 Jun 2021 19:50:46 +0300 Subject: ACPI: scan: Constify acpi_dma_supported() helper function Constify arguments to acpi_dma_supported(). The function doesn't need to change the content of the passed argument and when it's const it allows to supply the result of other functions that may return a pointer to a constant object.
