I have two minor comments:
* Patches to the qat driver have the following headline
crypto: qat -
* Checkpatch reports two alignment checks when it is run with --strict:
CHECK: Alignment should match open parenthesis
#33: FILE: drivers/crypto/qat/qat_common/adf_isr.c:248:
+ tasklet_setup(&priv_data->banks[i].resp_handler,
+ adf_response_handler);
CHECK: Alignment should match open parenthesis
#62: FILE: drivers/crypto/qat/qat_common/adf_sriov.c:57:
+ tasklet_setup(&vf_info->vf2pf_bh_tasklet,
+ adf_vf2pf_bh_handler);
total: 0 errors, 0 warnings, 2 checks, 83 lines checked
If you prefer I can resubmit this patch with these two changes.
Regards,
