Subject[PATCH 4.8 070/125] staging: sm750fb: Correctly set CLOCK_PHASE bit of display controller.
Date
4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Phil Turnbull <phil.turnbull@oracle.com>

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")
