[PATCH] i2c: Drop I2C_SMBUS_I2C_BLOCK_MAX
Drop I2C_SMBUS_I2C_BLOCK_MAX, use I2C_SMBUS_BLOCK_MAX instead. I2C_SMBUS_I2C_BLOCK_MAX has always been defined to the same value as I2C_SMBUS_BLOCK_MAX, and this will never change: setting it to a lower value would make no sense, setting it to a higher value would break i2c_smbus_data compatibility. There is no point in changing i2c_smbus_data to support larger block transactions in SMBus mode, as no SMBus hardware supports more than 32 byte blocks. Thus, for larger transactions, direct I2C transfers are the way to go. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
