Subject: [PATCH v2 5/5] drm/komeda: add rate limiting disable to err_verbosity
Date: Thu, 7 Nov 2019 11:42:44 +0000	[thread overview]
Message-ID: <20191107114155.54307-6-mihail.atanassov@arm.com> (raw)
In-Reply-To: <20191107114155.54307-1-mihail.atanassov@arm.com>

It's possible to get multiple events in a single frame/flip, so add an
option to print them all.
