From 9383f4c6b66256c039c65ddc141f0caeeae51847 Mon Sep 17 00:00:00 2001 From: Josh Cartwright Date: Thu, 13 Feb 2014 22:00:43 -0600 Subject: [PATCH] ACPI / platform: drop redundant ACPI_HANDLE check The acpi_dev_pm_attach/_detach functions perform their own checks to ensure the device has an ACPI companion. It is not necessary for the caller to do so. This mirrors what other busses with ACPI dev PM support do (i2c, spi, sdio). Cc: Len Brown Acked-by: Rafael J.
