linux-next: manual merge of the driver-core tree with the suspend tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Greg,

Today's linux-next merge of the driver-core tree got a conflict in
drivers/base/power/main.c between commit
de20f9bde404252647645f9f948c8c5de16cc51d ("PM: Asynchronous suspend and
resume of devices") from the suspend tree and commit
df5a0aec4591ae8a5deb67bc8cb6be3d0812abb2 ("drivers/base: Convert dev->sem
to mutex") from the driver-core tree.

I fixed it up (see below) and can carry the fix as necessary.
