[PATCH 5.13 067/104] drm/i915/bios: Fix ports mask

From: Greg Kroah-Hartman
Date: Mon Aug 02 2021 - 10:12:54 EST

From: Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx>

[ Upstream commit d7f237df53457cf0cbdb9943b9b7c93a05e2fdb6 ]

PORT_A to PORT_F are regular integers defined in the enum port,
while for_each_port_masked requires a bit mask for the ports.

Current given mask: 0b111
Desired mask: 0b111111

I noticed this while Christoph was reporting a bug found on headless
GVT configuration which bisect blamed commit 3ae04c0c7e63 ("drm/i915/bios:
limit default outputs to ports A through F")

v2: Avoid unnecessary line continuations as pointed by CI and Christoph
