checkpatch: fix __attribute__ matching
In the following code,
union thread_union init_thread_union
__attribute__((__section__(".data.init_task"))) =
{ INIT_THREAD_INFO(init_task) };
There is a non-conforming declaration. It should really be like the
following,
union thread_union init_thread_union
__attribute__((__section__(".data.init_task"))) = {
INIT_THREAD_INFO(init_task)
};
However, checkpatch doesn't catch this right now because it doesn't
correctly evaluate the "__attribute__".
It is not at all clear that we care what preceeds an assignment style
attribute when we find the open brace. Relax the test so we do not need
to check the __attribute__.
