macintosh: windfarm: Use unsigned type for 1-bit bitfields
stable inclusion from stable-v5.10.175 commit d47d364f6671d8794a89e4972b1fd3284d213c96 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8711T Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=d47d364f6671d8794a89e4972b1fd3284d213c96 -------------------------------- [ Upstream commit 748ea32d ] 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; ^ ~ drivers/macintosh/windfarm_smu_sensors.c:356:19: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion] pow->fake_volts = 1; ^ ~ drivers/macintosh/windfarm_smu_sensors.c:368:18: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion] 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.
