Subject: linux-next: manual merge of the input tree with the arm-soc tree
Hi Dmitry,
Today's linux-next merge of the input tree got a conflict in
drivers/input/keyboard/samsung-keypad.c between commit b3d6ac3e5f93
("input: samsung-keypad: Add device tree support") from the arm-soc tree
and commit 48c98b1bb85a ("Input: samsung-keypad - implement runtime power
management support") from the input tree.
I fixed it up (see below) and can carry the fix as necessary.

Cheers,
Stephen Rothwell sfr@...b.auug.org.au
