Subject: mlxsw: spectrum_span: Replace zero-length array with flexible-array member
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4780dbdbd957c204b62680161f39bb0bc4daf3a0;p=linux.git

mlxsw: spectrum_span: Replace zero-length array with flexible-array member

In a similar fashion to commit e99f8e7f88b5 ("mlxsw: Replace zero-length
array with flexible-array member"), use a flexible-array member to get a
compiler warning in case the flexible array does not occur last in the
structure.
