This is a note to let you know that I've just added the patch titled
iio: temperature: mlx90635: Fix ERR_PTR dereference in
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 a23c14b062d8800a2192077d83273bbfe6c7552d Mon Sep 17 00:00:00 2001 From: Harshit Mogalapalli harshit.m.mogalapalli@oracle.com Date: Mon, 13 May 2024 13:34:27 -0700 Subject: iio: temperature: mlx90635: Fix ERR_PTR dereference in mlx90635_probe()
When devm_regmap_init_i2c() fails, regmap_ee could be error pointer, instead of checking for IS_ERR(regmap_ee), regmap is checked which looks like a copy paste error.
