misc: ds1682: clean up ds1682_eeprom_read() and ds1682_eeprom_write()
The change removes redundant sysfs binary file boundary checks, since this task is already done on caller side in fs/sysfs/file.c Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
