Subject: net: remove some unless free on failure in alloc_netdev_mqs()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=92ff71b8fe9cd9c673615fc6f3870af7376d7c84;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

net: remove some unless free on failure in alloc_netdev_mqs()

When we jump to free_pcpu on failure in alloc_netdev_mqs()
rx and tx queues are not yet allocated, so no need to free them.
