Subject: [PATCH] Bluetooth: Remove spurious error message
Date: Wed, 12 May 2021 15:34:07 +0200	[thread overview]
Message-ID: <20210512133407.52330-1-szymon.janc@codecoup.pl> (raw)

Even with rate limited reporting this is very spammy and since
it is remote device that is providing bogus data there is no
need to report this as error.
