Subject: linux-next: manual merge of the wireless tree with the acpi tree
Hi John,
Today's linux-next merge of the wireless tree got a conflict in
drivers/platform/x86/toshiba_acpi.c between commit
76e310021ad9560fd02ce3d1e5723e5f0230ea7a ("toshiba_acpi: add full hotkey
support") from the acpi tree and commit
c6d660ce29295d344fcdc3654274b4a0aad1a9c8 ("rfkill: rewrite") from the
wireless tree.
I fixed it up (see below) and can carry the fix as necessary.

Cheers,
