media: netup_unidvb: fix irq init by register it at the end of probe
[ Upstream commit e6ad6233592593079db5c8fa592c298e51bc1356 ]
IRQ handler netup_spi_interrupt() takes spinlock spi->lock. The lock
is initialized in netup_spi_init(). However, irq handler is registered
before initializing the lock.
Spinlock dma->lock and i2c->lock suffer from the same problem.
Fix this by registering the irq at the end of probe.
