Subject: dm crypt: constify crypt_iv_operations structures
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1b1b58f54fdb1d28a85ab9e1b6d3d6b9b37f4ac7;p=linux-beck.git

dm crypt: constify crypt_iv_operations structures

The crypt_iv_operations are never modified, so declare them
as const.

Done with the help of Coccinelle.
