Firmware requests triggered by userspace action can be executed in interruptible context, which can cause signals to interrupt firmware loading. Ordinarily, one would propagate the error code to userspace and let it retry. However, request_firmware does not have proper handling of retryable errors, as sysfs fallbacks will clobber the original error code. Furthermore, pm_runtime, through which we would propagate the error code, doesn't support transient resume failures either. As such, as a quick fix, change to request_firmware_direct and retry it directly in situ 10 times.
