[06/16] crypto: atmel-{aes, sha, tdes} - Rename labels in probe()

Commit Message

Tudor Ambarus Dec. 5, 2019, 9:53 a.m. UTC

From: Tudor Ambarus <[e-mail]>

Choose label names which say what the goto does and not from where
the goto was issued. This avoids adding superfluous labels like
"err_aes_buff".
