Subject: crypto: stm32 - Remove unused hdev->err field
X-Git-Tag: v6.4-rc1~3^2~72
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=cfac232d4d86c4458787ea92b1b1d99225c6f29e;p=linux-block.git

crypto: stm32 - Remove unused hdev->err field

The variable hdev->err is never read so it can be removed.

Also remove a spurious inclusion of linux/crypto.h.
