[PATCH v3 04/19] crypto: caam: convert tasklets to use new tasklet_setup() API
From: Allen Pais <hidden>
Date: 2021-01-12 01:48:27
Also in:
linux-crypto, linux-rockchip, linux-samsung-soc
Subsystem:
crypto api, freescale caam (cryptographic acceleration and assurance module) driver, the rest · Maintainers:
Herbert Xu, "David S. Miller", Horia Geantă, Pankaj Gupta, Gaurav Jain, 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.
