From c577f4a5a08bb9677e12ddafb62e2f3a901de87f Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Sat, 30 Mar 2019 15:09:10 +0000 Subject: PCI: rockchip: Fix rockchip_pcie_ep_assert_intx() bitwise operations Currently the bitwise operations on the u16 variable 'status' with the setting ROCKCHIP_PCIE_EP_CMD_STATUS_IS are incorrect because ROCKCHIP_PCIE_EP_CMD_STATUS_IS is 1UL<<19 which is wider than the u16 variable. Fix this by making status a u32.
