[PATCH v1 0/3] Enable user helper interface for efi capsule update

[Kweh Hock Leong]

From: "Kweh, Hock Leong" <hock.leong.kweh@xxxxxxxxx>

Hi Guys,

This patchset is created on top of "efi: Capsule update support" patch:
http://permalink.gmane.org/gmane.linux.kernel.efi/4837

It leverages the request_firmware_nowait() to expose the user helper
interface for user to upload the capsule binary and calling the
efi_capsule_update() API to pass the binary to EFI firmware.

Besides build in kernel, the design also cater for build as kernel driver
module. This patchset introduce a new API (request_firmware_abort()) at
firmware_class so that the driver module could be unloaded by calling
the API to properly stop user helper interface and release the device.

Thanks.

  firmware loader: Introduce new API - request_firmware_abort()
  firmware loader: fix hung task warning dump
