Subject: [PATCH 3.12 070/119] Input: ili210x - fix permissions on "calibrate" attribute

From: Dmitry Torokhov <dmitry.torokhov@...il.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit b27c0d0c3bf3073e8ae19875eb1d3755c5e8c072 upstream.

"calibrate" attribute does not provide "show" methods and thus we should
not mark it as readable.
