[PATCH 0/3] net: ethernat: ezchip: bug fixing and code improvments
From: Pavel Skripkin
Date: Fri Jun 18 2021 - 12:14:36 EST
While manual code reviewing, I found some error in ezchip driver.
Two of them looks very dangerous:
1. use-after-free in nps_enet_remove
Accessing netdev private data after free_netdev()
2. wrong error handling of platform_get_irq()
It can cause passing negative irq to request_irq()
Also, in 2nd patch I removed redundant check to increase execution
speed and make code more straightforward.
