After the kernel update the module rtsx_pci is broken:
$ modprobe rtsx_pci
modprobe: ERROR: Error running install command '/bin/false' for module rtsx_pci: retcode 1
modprobe: ERROR: could not insert 'rtsx_pci': Invalid argument
My Realtek card reader is not working as a result. This is true for both 5.5.8 and the 5.4 branch.
