[ Upstream commit 6cc65be4f6f2a7186af8f3e09900787c7912dad2 ]
One of my tests compiles the kernel with gcc 4.5.3, and I hit the
following build error:
include/linux/semaphore.h: In function 'sema_init':
include/linux/semaphore.h:35:17: error: unknown field 'val' specified in initializer
include/linux/semaphore.h:35:17: warning: missing braces around initializer
include/linux/semaphore.h:35:17: warning: (near initialization for '(anonymous).raw_lock.<anonymous>.val')
I bisected it down to:
625e88be1f41 ("locking/qspinlock: Merge 'struct __qspinlock' into 'struct qspinlock'")
... which makes qspinlock have an anonymous union, which makes initializing it special
for older compilers. By adding strategic brackets, it makes the build
happy again.
