Subject: [PATCH] typec: tcpm: Fix incorrect 'and' operator
Date: Mon, 30 Apr 2018 08:23:06 -0500	[thread overview]
Message-ID: <20180430132305.GA20092@embeddedor.com> (raw)

Currently, logical and is being used instead of *bitwise* and.

Fix this by using a proper bitwise and operator.

Addresses-Coverity-ID: 1468455 ("Logical vs. bitwise operator")
Fixes: 64f7c494a3c0 ("typec: tcpm: Add support for sink PPS related messages")
