rtsx_usb module for Realtek Semiconductor Corp. RTS5139 Card Reader Controller doesn't load

[Matthew Haughton]

The module for Realtek Semiconductor Corp. RTS5139 Card Reader Controller (lsbusb ID 0bda:0139) does not load automatically on boot, so the SD card reader won't work.

If I add "rtsx_usb" to /etc/modules then the correct modules are loaded on boot and the SD card reader will work.

I use an ASUS N550JV. After updating from 13.1 to Factory, the card reader in not detected anymore. The driver now moved to rtsx_usb module and that is not loaded automatically. After modprobe rtsx_usb the card reader is working again.

This might be a bug in depmod. The device IDs are in the driver (which is how it actually loads when you modprobe it) but they're not getting picked up for modules.alias, which is what gets used for autoloading.

[Jeffm-9 (jeffm-9)]

Actually, no, it's much simpler. It's just not publishing its device table.

rtsx_usb: export device table

[Jeffm-9 (jeffm-9)]

This patch has been committed to the git master branch.

[Matthew Haughton (snafu109)]

Is apparently fixed upstream in http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1813908986e36119228c158aae1c6a0267c99e77 which should be included in an upcoming 3.16 release.

commit 35dca0e6c20e797175ce8c5f47b03630bb397af3 (drivers/mfd/rtsx_usb.c: export device table) in v3.16.3. Destined for release in 3.16.0-17.23

[Matthew Haughton (snafu109)]

Looks fixed with 3.16.0-17.23, change status to Fix Released? It wasn't mentioned in the changelog.
