Subject: [PATCH] liquidio CN23XX: check if PENDING bit is clear using logical and
Date: Fri, 18 Nov 2016 18:45:32 +0000	[thread overview]
Message-ID: <20161118184532.5282-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

the mbox state should be bitwise anded rather than logically anded
with OCTEON_MBOX_STATE_RESPONSE_PENDING. Fix this by using the
correct & operator instead of &&.
