Subject: [PATCH 4.2 187/258] pcmcia: sa11x0: fix missing clk_put() in sa11x0 socket drivers

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

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

From: Russell King <rmk+kernel@....linux.org.uk>

commit 72010aca55264cfe6516a955066c846d3885b0c6 upstream.

Fix the lack of clk_put() in sa11xx_base.c's error cleanup paths by
converting the driver to the devm_* API.

Fixes: 86d88bfca475 ("ARM: 8247/2: pcmcia: sa1100: make use of device clock")
