i2c-davinci build failure with Linux v4.0-3843-gbb0fd7ab0986

[Josh Boyer]

Hi All,

The i2c-davinci driver failed to build as a module with Linus' latest
tree as of this morning.  The error was:

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!
scripts/Makefile.modpost:90: recipe for target '__modpost' failed

It looks like commit 2e65676f710e (i2c: davinci: use bus recovery
infrastructure) likely introduced this error.  None of the i2c bus
recovery functions are exported from i2c-core.c that I can tell.

Was this commit tested as a modular build?

How embarassing. I meanwhile rely on the build-bots to do module
testing, but this failed here :( A patch was sent to -next a second ago
and I will send a pull-request to Linus ASAP. Thanks for the report!
