[libcamera-devel] [PATCH v2 03/10] libcamera: request: Add PFCError flag

[Jacopo Mondi]

From: Kieran Bingham via libcamera-devel <libcamera-devel at lists.libcamera.org>

Provide a new flag for the Request error state to indicate that a
per-frame control error has occurred. One or more controls set for this
request could not be guaranteed on this frame.
