Subject: [PATCH] ALSA: pcm: fix tracing reason in hw_ptr_error
Date: Fri, 25 Nov 2022 16:23:26 +0000	[thread overview]
Message-ID: <20221125162327.297440-1-john@metanate.com> (raw)

Strings need to be specially marked in trace events to ensure the
content is captured, othewise the trace just shows the value of the
pointer.
