i2c: core: Export bus recovery functions
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) Signed-off-by: Mark Brown <broonie@kernel.org> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
