commit 3253cf09146420bda0991eecc6fa9ab2268228e2
bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9

--------------------------------

[ Upstream commit 8fc9a77b ]

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