patch "iio: temperature: mlx90635: Fix ERR_PTR dereference in" added to char-misc-linus

[gregkh]

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.

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.
