2.6.32-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Pekka Paalanen <[email protected]> commit 635032cb397b396241372fa0ff36ae758e658b23 upstream. 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 Author: Kevin A. Granade <[email protected]> Date: Sat Sep 5 01:03:39 2009 -0500 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. Cc: Jakub Schmidtke <[email protected]> Cc: Kevin A.
