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. >>From eda7d0f38aaf50dbb2a2de15e8db386c4f6f65fc Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 8 Aug 2015 22:16:42 +0300 Subject: iio: accel: sca3000: memory corruption in sca3000_read_first_n_hw_rb() "num_read" is in byte units but we are write u16s so we end up write twice as much as intended.
