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

[RESEND 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 5.10-rc6 (b65054597872)

[Allen Pais]

From: Allen Pais <apais@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.

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

Hi Allen,

Thank you for the patch.

Please make sure to CC maintainers on changes to drivers they
maintain, otherwise it's hard to keep track. Thanks!
