[PATCH] crypto: caam - Remove unneeded 'ret' variable

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

 



From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>

Variable 'ret' is only used for returning the value 0.

We can make it simpler and just return 0 instead.

The semantic patch that makes this change is available
in scripts/coccinelle/misc/returnvar.cocci.
