[PATCH v5 06/19] crypto: ccp: convert tasklets to use new tasklet_setup() API
From: Allen Pais <hidden>
Date: 2021-02-08 09:50:17
Also in:
linux-crypto, linux-rockchip, linux-samsung-soc
Subsystem:
amd cryptographic coprocessor (ccp) driver, crypto api, the rest · Maintainers:
Tom Lendacky, John Allen, Herbert Xu, "David S. Miller", Linus Torvalds
From: Allen Pais <redacted> 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.
