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.
--- changelog v2: [PATCH 1/3] * use fw_lookup_buf() instead of __fw_lookup_buf() function call * move the fw_lookup_buf() function out of the CONFIG_PM_SLEEP block
[PATCH 2/3] * no change
[PATCH 3/3] * no change
