Ian Abbott c3c1defad2 staging: comedi: pcl818: Fix endian problem for AI command data ... commit 148e34fd33d53740642db523724226de14ee5281 upstream. The analog input subdevice supports Comedi asynchronous commands that use Comedi's 16-bit sample format. However, the call to `comedi_buf_write_samples()` is passing the address of a 32-bit integer parameter. On bigendian machines, this will copy 2 bytes from the wrong end of the 32-bit value. Fix it by changing the type of the parameter holding the sample value to `unsigned short`. [Note: the bug was introduced in commit edf4537bcb ("staging: comedi: pcl818: use comedi_buf_write_samples()") but the patch applies better to commit d615416de6 ("staging: comedi: pcl818: introduce pcl818_ai_write_sample()").] Fixes: d615416de6 ("staging: comedi: pcl818: introduce pcl818_ai_write_sample()") Cc: <stable@vger.kernel.org> # 4.0+ Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Link: https://lore.kernel.org/r/20210223143055.257402-10-abbotti@mev.co.uk Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-03-17 17:03:55 +01:00
