| Subject: i2c: core: Export bus recovery functions |
| |
| 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. |
| |
