Subject: linux-next: manual merge of the vfs tree with Linus' tree

Hi Al,

Today's linux-next merge of the vfs tree got a conflict in
drivers/usb/core/file.c between commit 469271f8c48f ("drivers: usb: core:
{file,hub,sysfs,usb}.c: Whitespace fixes") from Linus' tree and commit
e84f9e57b90c ("consolidate the reassignments of ->f_op in ->open()
instances") from the vfs tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
