Subject: [PATCH 5/5] i2c: mux: make use of __i2c_smbus_xfer
Date: Wed, 20 Jun 2018 10:51:57 +0200 [thread overview]
Message-ID: <20180620085157.30121-6-peda@axentia.se> (raw)
In-Reply-To: <20180620085157.30121-1-peda@axentia.se>
Calling the __i2c_smbus_xfer wrapper in __i2c_mux_smbus_xfer provides
retries and thus makes the parent-locked case consistent with the both
mux-locked (i2c_mux_smbus_xfer) and the I2C transfer cases.
