Subject: [PATCH] ALSA: pcxhr: use __func__ to get funcion's name in an output message
Date:   Sat, 31 Jul 2021 13:26:47 +0800
Message-Id: <20210731052647.141046-1-wangborong@cdjrlc.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Feedback-ID: bizesmtp:cdjrlc.com:qybgspam:qybgspam3
Precedence: bulk

Prefer using '"%s...", __func__' to get current function's name in
an output message.
