Bug Description

My integrated sdcard reader (realtek RTS525A accessed via PCI) works fine with kernels 5.15 but does not work anymore with kernels 5.19:
[ 48.704327] rtsx_pci 0000:3c:00.0: Unable to change power state from D0 to D3hot, device inaccessible
[ 53.741438] rtsx_pci 0000:3c:00.0: Unable to change power state from D3cold to D0, device inaccessible

This means that when inserting an sdcard into the reader, the media is not seen (and there is no new device in /dev).

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...
