2015-04-03char: xillybus: Don't return -EFAULT on user-triggered flushEli Billauer
The API allows the application to flush a host-to-FPGA stream by calling write() with the data count set to zero. Before this patch, copy_from_user() was called with a non-zero byte count, which possibly made it attempt to read from unmapped user memory. Such attempts caused the driver to return -EFAULT instead of 0, even though the desired operation went through fine. This patch ensures the driver returns 0 on a successful flush.

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-09-24xillybus: Move out of stagingEli Billauer
This driver has been functional and stable throughout the year it has spent in the staging area. It has been patched for minor bugs, coding style issues and improvements during this period. This is the second submission of this move-out, after making several style improvements, as suggested by Dan Carpenter.
