This is a note to let you know that I've just added the patch titled
Staging: asus_oled: fix image processing
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git

The patch will show up in the next release of the linux-next tree

Subject: Staging: asus_oled: fix image processing
Programming an image was broken, because odev->buf_offs was not advanced
for val == 0 in append_values(). This regression was introduced in:
commit 1ff12a4aa354bed093a0240d5e6347b1e27601bc

Staging: asus_oled: Cleaned up checkpatch issues.
Fix the image processing by special-casing val == 0.
I have tested this change on an Asus G50V laptop only.
