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 also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From 18dfb5326370991c81a6d1ed6d1aeee055cb8c05 Mon Sep 17 00:00:00 2001 From: Mathieu Othacehe Date: Sun, 3 May 2020 11:29:55 +0200 Subject: iio: vcnl4000: Fix i2c swapped word reading. The bytes returned by the i2c reading need to be swapped unconditionally. Otherwise, on be16 platforms, an incorrect value will be returned. Taking the slow path via next merge window as its been around a while and we have a patch set dependent on this which would be held up.
