[PATCH AUTOSEL 4.14 8/8] net: sfp: fix memory leak in sfp_probe()

[Sasha Levin]

From: Jianglei Nie <niejianglei2021@xxxxxxx>

[ Upstream commit 0a18d802d65cf662644fd1d369c86d84a5630652 ]

sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When
devm_add_action() fails, sfp is not freed, which leads to a memory leak.

We should use devm_add_action_or_reset() instead of devm_add_action().
