This is a > clean up, no functional change. > The new macro contains compile-time test to verify N is in suitable > range. The test works such that it multiplies constant N by constant > double-negation of size of a non-empty structure, i.e. it multiplies > constant N by constant 1 in each successful compilation case. > The non-empty structure may contain C11 _Static_assert(), make use of > this and place the kernel variant of static assert in there, so that > it performs the compile-time check for N in the correct range. Note > that it is not possible to directly use static_assert in compound > statements, hence this convoluted construct. > Signed-off-by: Marek Vasut > Cc: Fabio Estevam > Cc: Peng Fan > Cc: Stefano Babic Applied to u-boot-imx, master, thanks !
