This is a note to let you know that I've just added the patch titled iio: adc: stm32: fix bad error check on max_channels 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. >From 4fb840c95f82652cece7352be9080884cafb92a0 Mon Sep 17 00:00:00 2001 From: Fabrice Gasnier <fabrice.gasnier@xxxxxx> Date: Mon, 18 Sep 2017 18:24:15 +0200 Subject: iio: adc: stm32: fix bad error check on max_channels Fix a bad error check when counting 'st,adc-channels' array elements. This is seen when all channels are in use simultaneously.
