Subject: crypto: use ERR_CAST
From: Julia Lawall <julia@xxxxxxx>

Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)).  The former makes more
clear what is the purpose of the operation, which otherwise looks like a
no-op.

The semantic patch that makes this change is as follows:

- ERR_PTR(PTR_ERR(x))
+ ERR_CAST(x)
