drm/tidss: Fix race condition while handling interrupt registers
commit a9a73f2661e6f625d306c9b0ef082e4593f45a21 upstream.
The driver has a spinlock for protecting the irq_masks field and irq
enable registers. However, the driver misses protecting the irq status
registers which can lead to races.
Take the spinlock when accessing irqstatus too.
