Re: RTS5229 built in card reader not detected after Linux 5.0.x

This bug is also present on the Intel NUC7CJYH board, which uses the RTS5229 PCI Express Card reader.
Kernel >= 5.1 fails to detect any SD card. Nothing shows up when running lsblk.

Also tried 
# udevadm monitor

while inserting a card. Still no output.
Downgrading the kernel to < 5.1 solves the problem.

I did a tracing of kernel mmc events on kernel 5.0.13 and 5.2.2, whilst inserting a card, see the attachments. 
According to the trace, all mmc requests return cmd_err=-110 on kernel 5.2.2.
