patch "iio: magnetometer: tlv493d: remove erroneous shift in X-axis data" added to char-misc-linus

[gregkh]

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

    iio: magnetometer: tlv493d: remove erroneous shift in X-axis data

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: magnetometer: tlv493d: remove erroneous shift in X-axis data

TLV493D_BX2_MAG_X_AXIS_LSB is defined as GENMASK(7, 4). FIELD_GET()
already right-shifts bits [7:4] to [3:0], so the additional >> 4
discards most of the X-axis low nibble. The Y and Z axes correctly
omit this extra shift. Remove it.
