From: Antoniu Miclaus <antoniu.miclaus@xxxxxxxxxx> [ Upstream commit 6f6bd7591945c679b7f595119ea997b19f5794db ] The warning comes from __BF_FIELD_CHECK() specifically BUILD_BUG_ON_MSG(__builtin_constant_p(_val) ? \ ~((_mask) >> __bf_shf(_mask)) & (_val) : 0, \ _pfx "value too large for the field"); \ The code was using !(enum value) which is not particularly easy to follow so replace that with explicit matching and use of ? 0 : 1; or ? 1 : 0; to improve readability.
