This is a note to let you know that I've just added the patch titled mfd: t7l66xb: Drop platform disable callback to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mfd-t7l66xb-drop-platform-disable-callback.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 3f99f8163b0ae8606fe0cb50380dcc48319713f5 Author: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> Date: Mon May 30 21:24:28 2022 +0200 mfd: t7l66xb: Drop platform disable callback [ Upstream commit 128ac294e1b437cb8a7f2ff8ede1cde9082bddbe ] None of the in-tree instantiations of struct t7l66xb_platform_data provides a disable callback. So better don't dereference this function pointer unconditionally. As there is no user, drop it completely instead of calling it conditional. This is a preparation for making platform remove callbacks return void.
