Subject: [PATCH] mtd: bcm47xxsflash: use platform_(set|get)_drvdata
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We have generic place & helpers for storing platform driver data so
there is no reason for using custom priv pointer.

This allows cleaning up struct bcma_sflash from unneeded fields.
