V4L/DVB: ir: Make sure that the spinlocks are properly initialized
Some spinlocks are not properly initialized on ir core: [ 471.714132] BUG: spinlock bad magic on CPU#0, modprobe/1899 [ 471.719838] lock: f92a08ac, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0 [ 471.727301] Pid: 1899, comm: modprobe Not tainted 2.6.33 #36 [ 471.733062] Call Trace: [ 471.735537] [<c1498793>] ? printk+0x1d/0x22 [ 471.739866] [<c12694e3>] spin_bug+0xa3/0xf0 [ 471.744224] [<c126962d>] do_raw_spin_lock+0x7d/0x160 [ 471.749364] [<f92a01ff>] ? ir_rc5_register+0x6f/0xf0 [ir_rc5_decoder] So, use static initialization for the static spinlocks, instead of the dynamic ones (currently used), as proposed by David Härdeman on one of his RFC patches.
