Wysocki Date: Tue, 11 Feb 2020 22:58:26 +0000 (+0100) Subject: PM: QoS: Drop the PM_QOS_SUM QoS type X-Git-Tag: v5.7-rc1~187^2~4^2~27 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=87ad7356799622b69478076cd99df7a5024992cb;p=thirdparty%2Fkernel%2Fstable.git PM: QoS: Drop the PM_QOS_SUM QoS type The PM_QOS_SUM QoS type is not used, so drop it along with the code referring to it in pm_qos_get_value() and the related local variables in there. No intentional functional impact. Signed-off-by: Rafael J.
