4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mimi Zohar <zohar@xxxxxxxxxxxxxxxxxx>
[ Upstream commit fd90bc559bfba743ae8de87ff23b92a5e4668062 ]
Don't differentiate, for now, between kernel_read_file_id READING_FIRMWARE
and READING_FIRMWARE_PREALLOC_BUFFER enumerations.
Fixes: a098ecd firmware: support loading into a pre-allocated buffer (since 4.8)
