From 4e353ff40a830c9c5a9feee13d1cacbc3f803e8f Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 16 Dec 2022 10:21:25 -0600 Subject: [PATCH] PCI: switchtec: Simplify switchtec_dma_mrpc_isr() The "ret" variable in switchtec_dma_mrpc_isr() is superfluous. Remove it and just return the value. No functional change intended.
