2021-06-12staging: drop kpc2000 driverGreg Kroah-Hartman1-222/+0
It seems that the old developer is no longer with the company producing this device, and the company has no plans on getting this out of the staging directory at all, so let's drop the driver for now as it's pretty much abandonded. If someone want to support this and get it out of staging, we can easily revert this change and bring it back.

2019-06-13staging: kpc2000: removed DMA AIO implementation.Jeremy Sowden1-2/+0
The existing implementation for doing DMA via asynchronous IO didn't work and there was no longer a use-case for it. Removed it. Fixed a few checkpatch warnings about too-long lines and extraneous braces in the process.
