From ec91df8d3faf90d1cb428a7c4950995c6514d0ab Mon Sep 17 00:00:00 2001 From: Karthikeyan Ramasubramanian Date: Thu, 3 May 2018 14:14:39 -0600 Subject: [PATCH] tty: serial: qcom_geni_serial: Return IRQ_NONE for spurious interrupts Currently the driver returns IRQ_HANDLED when spurious interrupts happen. This is misleading. Fix the behavior by returning IRQ_NONE for spurious interrupts.
