This is a note to let you know that I've just added the patch titled

Revert "hwmon: (lm80) fix a missing check of bus read in lm80 probe"

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-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: Greg Kroah-Hartman gregkh@linuxfoundation.org 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.
