patch "staging: sm750fb: Fix bugs introduced by early commits" added to staging-linus

[gregkh]

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

    staging: sm750fb: Fix bugs introduced by early commits

to my staging git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-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: staging: sm750fb: Fix bugs introduced by early commits

Early commit 30ca5cb63c56965 ("staging: sm750fb: change definition of
PANEL_PLANE_TL fields") and 27b047bbe1ee9c0 ("staging: sm750fb: change
definition of PANEL_PLANE_BR fields") modify the register bit fields
definitions. But the modifications are wrong, because the bit mask of
"bit field 10:0" is not 0xeff, but 0x7ff. The wrong definition bugs
makes display very strange.
