Subject[PATCH 3.14 80/92] i2c: core: Export bus recovery functions
Date
3.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Mark Brown <broonie@kernel.org>

commit c1c21f4e60ed4523292f1a89ff45a208bddd3849 upstream.

Current -next fails to link an ARM allmodconfig because drivers that use
the core recovery functions can be built as modules but those functions
are not exported:

ERROR: "i2c_generic_gpio_recovery" [drivers/i2c/busses/i2c-davinci.ko] undefined!
ERROR: "i2c_generic_scl_recovery" [drivers/i2c/busses/i2c-davinci.ko] undefined!
ERROR: "i2c_recover_bus" [drivers/i2c/busses/i2c-davinci.ko] undefined!

Add exports to fix this.

Fixes: 5f9296ba21b3c (i2c: Add bus recovery infrastructure)
