#     macintosh: windfarm: Use unsigned type for 1-bit bitfields
#     
#     Clang warns:
#     
#       drivers/macintosh/windfarm_lm75_sensor.c:63:14: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion]
#                       lm->inited = 1;

#                       pow->fake_volts = 1;

#                       pow->quadratic = 1;
#                                      ^ ~
#     
#     There is no bug here since no code checks the actual value of these
#     fields, just whether or not they are zero (boolean context), but this
#     can be easily fixed by switching to an unsigned type.
