Sergey Shtylyov cb834ff29b i2c: jz4780: add IRQ check
[ Upstream commit c5e5f7a8d9 ]

The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to devm_request_irq() (which
takes *unsigned* IRQ #), causing it to fail with -EINVAL, overriding
an original error code.  Stop calling devm_request_irq() with invalid
IRQ #s.
