From db02e176f597a14eb696141ffa008c2429453a15 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Wed, 6 Dec 2023 16:42:31 -0600 Subject: [PATCH] PCI/AER: Use explicit register sizes for struct members aer_irq() reads the AER Root Error Status and Error Source Identification (PCI_ERR_ROOT_STATUS and PCI_ERR_ROOT_ERR_SRC) registers directly into struct aer_err_source. Both registers are 32 bits, so declare the members explicitly as "u32" instead of "unsigned int". Similarly, aer_get_device_error_info() reads the AER Header Log (PCI_ERR_HEADER_LOG) registers, which are also 32 bits, into struct aer_header_log_regs. Declare those members as "u32" as well. No functional changes intended.
