[ Upstream commit 147178cf03a6dcb337e703d4dacd008683022a58 ]
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 the
invalid IRQ #s.
