[libcamera-devel] [PATCH v3 07/11] libcamera: v4l2_videodevice: Prevent shadowing of V4L2BufferCache members

Kieran Bingham kieran.bingham at ideasonboard.com
Fri Oct 16 11:00:10 CEST 2020


The members free, and lastUsed were not following the libcamera coding
style, and were producing a shadowed parameter on the construction.

Rename them to be marked as member variables with the _ postfix
accordingly.
