Summary
dma-buf/sw-sync: don't enable IRQ from sync_print_obj()
Details

In the Linux kernel, the following vulnerability has been resolved:

dma-buf/sw-sync: don't enable IRQ from syncprintobj()

Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from known context") by error replaced spinunlockirqrestore() with spinunlockirq() for both syncdebugfsshow() and syncprintobj() despite syncprintobj() is called from syncdebugfsshow(), lockdep complains inconsistent lock state warning.

Use plain spin_{lock,unlock}() for syncprintobj(), for syncdebugfsshow() is already using spin_{lock,unlock}_irq().
