[PATCH 00/42] crypto: Convert to platform remove callback returning void

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

this series converts all platform drivers below drivers/crypto to use
.remove_new(). Compared to the traditional .remove() callback
.remove_new() returns no value. This is a good thing because the driver
core doesn't (and cannot) cope for errors during remove. The only effect
of a non-zero return value in .remove() is that the driver core emits a
warning. The device is removed anyhow and an early return from .remove()
usually yields resource leaks and/or use-after-free bugs.

There are three drivers that got that wrong and potentially returned an
error code (caam/jr.c, stm32/stm32-crc32.c, stm32/stm32-cryp.c). These
are fixed accordingly. The other drivers could be transformed trivially.

See commit 5c5a7680e67b ("platform: Provide a remove callback that
returns no value") for an extended explanation and the eventual goal.

There are no interdependencies in this series. As there are still quite
a few drivers to convert, I'm happy about every patch that makes it in.
So even if there is a merge conflict with one patch until you apply (or
a different concern that doesn't apply to all patches), please apply the
remainder of this series anyhow. I'll come back to the part that you
(maybe) skipped at a later point.

Best regards and thanks
Uwe
