This is a note to let you know that I've just added the patch titled
nvmem: release the write-protect pin
to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-next 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 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: Khouloud Touil ktouil@baylibre.com Date: Tue, 10 Mar 2020 13:22:50 +0000 Subject: nvmem: release the write-protect pin
Put the write-protect GPIO descriptor in nvmem_release() so that it can be automatically released when the associated device's reference count drops to 0.
