Subject: [RESEND PATCH v2 4/9] soundwire: export sdw_write/read_no_pm functions
Date:   Fri, 22 Jan 2021 15:06:29 +0800
Message-Id: <20210122070634.12825-5-yung-chuan.liao@linux.intel.com>
In-Reply-To: <20210122070634.12825-1-yung-chuan.liao@linux.intel.com>
References: <20210122070634.12825-1-yung-chuan.liao@linux.intel.com>
Precedence: bulk

sdw_write_no_pm and sdw_read_no_pm are useful when we want to do IO
without touching PM.

Fixes: 0231453bc08f ('soundwire: bus: add clock stop helpers')
Fixes: 60ee9be25571 ('soundwire: bus: add PM/no-PM versions of
read/write functions')
