This is a note to let you know that I have just added a patch titled i2c: core: Export bus recovery functions to the linux-3.13.y-queue branch of the 3.13.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11-ckt21. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From bccbeee0d5a9a6b3b0eb03e762356f259c5e4b1f Mon Sep 17 00:00:00 2001 From: Mark Brown <broonie@kernel.org> Date: Wed, 15 Apr 2015 19:18:39 +0100 Subject: i2c: core: Export bus recovery functions 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.
