Subject[PATCH] USB: EHCI: ehci-mv: fix error handling in mv_ehci_probe()
Date
If the function platform_get_irq() failed, the negative value
returned will not be detected here. So fix error handling in
mv_ehci_probe(). And when get irq failed, the function
platform_get_irq() logs an error message, so remove redundant
message here.
