Subject: Re: [PATCH][next] drm/i915/hdcp: Fix return of value in uninitialized
variable ret

From: Colin Ian King <redacted>

Currently when there are other connectors on the port using HDCP the
function _intel_hdcp_disable returns a garbage uninitialized value in
variable ret.  I believe the intention is to return 0, so return this
literal value instead of the value in ret.

Addresses-Coverity: ("Uninitialized scalar return")
Fixes: 899c8762f981 ("drm/i915/hdcp: Configure HDCP2.2 MST steram
encryption status")

Thanks, but there's already a fix in progress:
