Subject: patch "iio: accel: adxl372: Fix push to buffers lost samples" added to staging-linus
Date: Thu, 10 Oct 2019 11:20:04 +0200 [thread overview]
Message-ID: <157069920469209@kroah.com> (raw)
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.

Subject: iio: accel: adxl372: Fix push to buffers lost samples
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.
