Subject: PCI: pcie, aer: init struct aer_err_info for reuse
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1b4ffcf8432f7945e0bd0571f10a2f2bd1dbd850;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

PCI: pcie, aer: init struct aer_err_info for reuse

In case of multiple errors, struct aer_err_info would be reused among
all reported devices.  So the info->status should be initialized before
recycled.  Otherwise error of one device might be reported as the error
of another device.  Also info->flags has similar problem on reporting
TLP header.
