Subject: [PATCH 3.16.y-ckt 101/170] mtd: m25p80: get rid of spi_get_device_id

3.16.7-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= <zajec5@...il.com>

commit 90e55b3812a1245bb674afcc4410ddba7db402f6 upstream.

This simplifies the way we use spi_nor framework and will allow us to
drop spi_nor_match_id.
