stable inclusion from stable-5.10.65 commit 46638d6941ee55fec7a8c62abdb7cece0e231fe8 bugzilla: 182361 https://gitee.com/openeuler/kernel/issues/I4EH3U
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 4ac5132e8a4300637a2da8f5d6bc7650db735b8a ]
The driver neglects to check the result of platform_get_irq()'s call and blithely passes the negative error codes to usb_add_hcd() (which takes *unsigned* IRQ #), causing request_irq() that it calls to fail with -EINVAL, overriding an original error code. Stop calling usb_add_hcd() with the invalid IRQ #s.
