Revision 8788994376d84d627450fd0d67deb6a66ddf07d7 authored by Rikard Falkeborn on 05 December 2019, 00:50:20 UTC, committed by Linus Torvalds on 05 December 2019, 03:44:12 UTC
Having BUILD_BUG_ON_ZERO produce a value of type size_t leads to awkward
casts in cases where the result needs to be signed, or of smaller type
than size_t.  To avoid this, cast the value to int instead and rely on
implicit type conversions when a larger or unsigned type is needed.
