Subject: [PATCH][V2] dm ioctl: make dm_open and dm_release release static

From: Colin Ian King <colin.king@...onical.com>

Making dm_open and dm_release static fixes the sparse warnings:

warning: symbol 'dm_open' was not declared. Should it be static?
warning: symbol 'dm_release' was not declared. Should it be static?

Fixes: ab2c6224f4c0c ("dm: a basic support for using the select or poll function")
