X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c40f716ad34170aec93da145210aacf10599ecb0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git tty: serial: pci: constify pci_device_id. pci_device_id are not supposed to change at runtime. All functions working with pci_device_id provided by work with const pci_device_id. So mark the non-const structs as const.
