[PATCH v3 00/19]crypto: convert tasklets to use new tasklet_setup API()

[PATCH v3 00/19]crypto: convert tasklets to use new tasklet_setup API()

[Allen Pais]

From: Allen Pais <apais@linux.microsoft.com>

Commit 12cc923f1ccc ("tasklet: Introduce new initialization API")
introduced a new tasklet initialization API. This series converts
all the crypto modules to use the new tasklet_setup() API

The series is based on v5.11-rc2 (e71ba9452f0b)

v3:
  - fixed rockchip driver(Emil Renner Berthing)

v2:
  - added acks
  - addressed comments [Krzysztof and Gilad]

[PATCH v3 06/19] crypto: ccp: convert tasklets to use new tasklet_setup() API

[Allen Pais]

From: Allen Pais <apais@linux.microsoft.com>

In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.

[PATCH v3 12/19] crypto: omap: convert tasklets to use new tasklet_setup() API

[Allen Pais]

From: Allen Pais <apais@linux.microsoft.com>

In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.

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,
