patch "iio: light: al3010: fix incorrect scale for the highest gain range" added to char-misc-linus

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

iio: light: al3010: fix incorrect scale for the highest gain range

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: light: al3010: fix incorrect scale for the highest gain range

al3010_scales[] encodes the highest gain range as {0, 1187200}. For IIO_VAL_INT_PLUS_MICRO, the fractional part must be less than 1000000, so the scale 1.1872 should instead be represented as { 1, 187200 }.

Since write_raw() compares the value from userspace against this table, writing the advertised 1.1872 scale never matches the malformed entry and returns -EINVAL. As a result, the highest gain range cannot be selected. Reading the scale in that state also reports the malformed value.
