From: Len Brown Date: Sun, 27 Dec 2009 03:04:03 +0000 (-0500) Subject: ACPI: hp-wmi, msi-wmi: clarify that wmi_install_notify_handler() returns an acpi_status X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f27725756be8a2c2dc65eaf70d0b52807aa2f113;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ACPI: hp-wmi, msi-wmi: clarify that wmi_install_notify_handler() returns an acpi_status Emphasize that that wmi_install_notify_handler() returns an acpi_status rather than -errno by by testing ACPI_SUCCESS(), ACPI_FAILURE(). No functional change in this patch, but this confusion caused a bug in dell-wmi.
