This is a note to let you know that I've just added the patch titled staging: most: cdev: fix chrdev_region leak in mod_exit 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-testing 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 be merged to the staging-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From af708900e9a48c0aa46070c8a8cdf0608a1d2025 Mon Sep 17 00:00:00 2001 From: Suresh Udipi <sudipi@xxxxxxxxxxxxxx> Date: Wed, 24 Apr 2019 21:23:43 +0200 Subject: staging: most: cdev: fix chrdev_region leak in mod_exit It looks like v4.18-rc1 commit [0] which upstreams mld-1.8.0 commit [1] missed to fix the memory leak in mod_exit function.
