[PATCH 5.0 110/146] drm/i915/icl: Fix the TRANS_DDI_FUNC_CTL2 bitfield macro

[Greg Kroah-Hartman]

5.0-stable review patch.  If anyone has any objections, please let me know.

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

From: Manasi Navare <manasi.d.navare@xxxxxxxxx>

commit 69903dfae0310afe8a15f5cd4e376ebb7c6da1d2 upstream.

This patch fixes the PORT_SYNC_MODE_MASTER_SELECT macro
to correctly do the left shifting to set the port sync
master select correctly.
I have tested this fix on ICL.
