Prado [ Upstream commit 25d70702142ac2115e75e01a0a985c6ea1d78033 ] Commit a23aa0404218 ("net: stmmac: ethtool: Fixed calltrace caused by unbalanced disable_irq_wake calls") introduced checks to prevent unbalanced enable and disable IRQ wake calls. However it only initialized the auxiliary variable on one of the paths, stmmac_request_irq_multi_msi(), missing the other, stmmac_request_irq_single(). Add the same initialization on stmmac_request_irq_single() to prevent "Unbalanced IRQ wake disable" warnings from being printed the first time disable_irq_wake() is called on platforms that run on that code path.
