patch "iio: imu: inv_icm42600: Fix I2C init possible nack" added to char-misc-linus

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

iio: imu: inv_icm42600: Fix I2C init possible nack

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: imu: inv_icm42600: Fix I2C init possible nack

This register write to REG_INTF_CONFIG6 enables a spike filter that is impacting the line and can prevent the I2C ACK to be seen by the controller. So we don't test the return value.
