4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Phil Turnbull <phil.turnbull@xxxxxxxxxx>
commit 992f961480d23e9ef9e686e512a419efef723523 upstream.
Commit 6fba39cf32a3 ("staging: sm750fb: use BIT macro for
PANEL_DISPLAY_CTRL single-bit fields") accidentally changed the
CLOCK_PHASE logic from '|=' to '=' which clears all the previously set
bits.
Fixes: 6fba39cf32a3 ("staging: sm750fb: use BIT macro for PANEL_DISPLAY_CTRL single-bit fields")
