The outputs of lspci also slightly differ for kernel 5.15 and kernel 5.19. On 5.15, it reports:
3c:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS525A PCI Express Card Reader (rev 01)
On 5.19, it reports:
3c:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS525A PCI Express Card Reader (rev ff)
So I guess this is a bug in the driver...
