I got a new laptop and I install Debian Jessie, but the SD Card reader is not working at all.
When I list the devices with lspci it list the device:
07:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5249 PCI Express Card Reader (rev 01)
But it doesn't work. I snoop around in the net and I found that the kernel is supporting the card reader but it is not included.
The source file is in
drivers/mfd/rts5249.c
How can I compile and install it, so I can start up the device?
Thanks in advance.
