In firmware_loading_timeout(), *int* result of __firmware_loading_timeout() multiplied by HZ might overflow before being implicitly cast to *long* when being returned. Rewrite the function using check_mul_overflow() and capping the result at LONG_MAX on actual overflow... Found by Linux Verification Center (linuxtesting.org) with the Svace static analysis tool.
