Bluetooth: hci_bcm: Check for error irq
[ Upstream commitb38cd3b42f
] For the possible failure of the platform_get_irq(), the returned irq could be error number and will finally cause the failure of the request_irq(). Consider that platform_get_irq() can now in certain cases return -EPROBE_DEFER, and the consequences of letting request_irq() effectively convert that into -EINVAL, even at probe time rather than later on. So it might be better to check just now. Fixes:0395ffc1ee
