[PATCH] net: mana: Fix memory leak in mana_hwc_create_wq

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

 



If allocating the DMA buffer fails, mana_hwc_destroy_wq was called
without previously storing the pointer to the queue.

In order to avoid leaking the pointer to the queue, store it as soon as
it is allocated.
