patch "staging: comedi: me4000: Fix endian problem for AI command data" added to staging-linus

This is a note to let you know that I've just added the patch titled

staging: comedi: me4000: Fix endian problem for AI command data

to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

Subject: staging: comedi: me4000: Fix endian problem for AI command data

The analog input subdevice supports Comedi asynchronous commands that use Comedi's 16-bit sample format. However, the calls to comedi_buf_write_samples() are passing the address of a 32-bit integer variable. 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 variable holding the sample value to unsigned short.
