[PATCH 07/11] checkpatch: complex macro should allow the empty do while loop

[Andy Whitcroft <apw@canonical.com>]

It is common to stub out a function as below, this is triggering a
complex macro format incorrectly.  Sort this out:

    #define cma_early_regions_reserve(reserve)   do { } while (0)
