How to enable rts5139 kernel module?
I have an Acer S3. It has a card reader and It seems I can make it work by enabling the rts5139 module.
Right now, modprobe rts5139 gives an error. The module is not present. But a search in my hard drive reveals that there's a Makefile in some directory with that name:
$ locate rts5139
/usr/src/kernels/3.3.0-4.fc16.x86_64/drivers/staging/rts5139
/usr/src/kernels/3.3.0-4.fc16.x86_64/drivers/staging/rts5139/Kconfig
/usr/src/kernels/3.3.0-4.fc16.x86_64/drivers/staging/rts5139/Makefile
It's been several years since I last compiled a kernel. What are these "staging" drivers?
How do I enable one of them?
