Subject: linux-next: manual merge of the devicetree tree with the i2c tree
Date: Wed, 26 Nov 2014 15:33:53 +1100 [thread overview]
Message-ID: <20141126153353.5f4fedd5@canb.auug.org.au> (raw)
[-- Attachment #1: Type: text/plain, Size: 4264 bytes --]
Hi Grant,
Today's linux-next merge of the devicetree tree got a conflict in
drivers/i2c/i2c-core.c between commit 2fd36c552649 ("i2c: core: Map OF
IRQ at probe time") from the i2c tree and commit a430a3455f2c
("i2c/of: Factor out Devicetree registration code") from the devicetree
tree.
I fixed it up (thanks for the heads up, but please see below) and can
carry the fix as necessary (no action is required).

Cheers,
