I2C: mv64xxx: remove I2C_M_NOSTART code
As this driver does not advertise protocol mangling support (I2C_FUNC_PROTOCOL_MANGLING is not set), having code to act on I2C_M_NOSTART is illogical, and in any case isn't supportable on anything but the first message - which makes no sense. Remove the I2C_M_NOSTART code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Mark A. Greer <mgreer@animalcreek.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
