Subject: [SCSI] bnx2fc: code cleanup in bnx2fc_offload_session
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5fb8fd0dbc0f7e3bc3ea594223e5d4b50c2092d9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[SCSI] bnx2fc: code cleanup in bnx2fc_offload_session

- Free session resources before rport logoff
- Do not free session resources in bnx2fc_alloc_session_resc() as it is handled
  in caller's error handling path.
- Do not call bnx2fc_free_session_resc() if bnx2fc_init_tgt() fails as cq_lock
  is not yet initialized.
