409 This driver supports driver model based binding through board
410 specific I2C device tables.
411
412 It also supports the "legacy" style of driver binding. To use
413 that with some chips which don't replicate LM75 quirks exactly,
414 you may need the "force" module parameter.

405 This driver can also be built as a module. If so, the module 416 This driver can also be built as a module. If so, the module
406 will be called lm75. 417 will be called lm75.
