This is a note to let you know that I've just added the patch titled
iio: accel: adxl372: Fix push to buffers lost samples
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.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.

One in two sample sets was lost by multiplying fifo_set_size with sizeof(u16). Also, the double number of available samples were pushed to the iio buffers.
