Title
net: fec: remove .ndo_poll_controller to avoid deadlocks
Summary
In the Linux kernel, the following vulnerability has been resolved: net: fec: remove .ndo_poll_controller to avoid deadlocks There is a deadlock issue found in sungem driver, please refer to the commit ac0a230f719b ("eth: sungem: remove .ndo_poll_controller to avoid deadlocks"). The root cause of the issue is that netpoll is in atomic context and disable_irq() is called by .ndo_poll_controller interface of sungem driver, however, disable_irq() might sleep. After analyzing the implementation of fec_poll_controller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX completions, the .ndo_poll_controller is unnecessary to be implemented in the fec driver, so fec_poll_controller() can be safely removed.

The root cause of the issue is that netpoll is in atomic\ncontext and disable_irq() is called by .ndo_poll_controller interface\nof sungem driver, however, disable_irq() might sleep. After analyzing\nthe implementation of fec_poll_controller(), the fec driver should have\nthe same issue. Due to the fec driver uses NAPI for TX completions, the\n.ndo_poll_controller is unnecessary to be implemented in the fec driver,\nso fec_poll_controller() can be safely removed."
