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 99ae3417672a6d4a3bf68d4fc43d7c6ca074d477 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 3 May 2021 13:56:31 +0200 Subject: Revert "hwmon: (lm80) fix a missing check of bus read in lm80 probe" This reverts commit 9aa3aa15f4c2f74f47afd6c5db4b420fadf3f315. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, it was determined that this commit is not needed at all so just revert it. Also, the call to lm80_init_client() was not properly handled, so if error handling is needed in the lm80_probe() function, then it should be done properly, not half-baked like the commit being reverted here did.
