[PATCH 6.12 331/590] RDMA/srp: Fix error handling in srp_add_port

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ma Ke <make_ruc2021@xxxxxxx>

[ Upstream commit a3cbf68c69611188cd304229e346bffdabfd4277 ]

As comment of device_add() says, if device_add() succeeds, you should
call device_del() when you want to get rid of it. If device_add() has
not succeeded, use only put_device() to drop the reference count.

Add a put_device() call before returning from the function to decrement
reference count for cleanup.

Found by code review.
