[PATCH][REPOST] lpfc: Fix dma virtual address ptr assignment in bsg

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

 



lpfc_bsg_ct_unsol_event routine acts assigns a ct_request to the
wrong structure address, resulting in a bad address that results
in bsg related timeouts.

Correct the ct_request assignment to use the kernel virtual buffer
address (not the control structure address).
