Subject: [PATCH 4.14 15/21] macintosh: windfarm: Use unsigned type for 1-bit bitfields
Date: Wed, 15 Mar 2023 13:12:38 +0100 [thread overview]
Message-ID: <20230315115719.390590317@linuxfoundation.org> (raw)
In-Reply-To: <20230315115718.796692048@linuxfoundation.org>
From: Nathan Chancellor <nathan@kernel.org>
[ Upstream commit 748ea32d2dbd813d3bd958117bde5191182f909a ]
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.
