Subject: [media] gspca: reset image_len to 0 on LAST_PACKET when discarding frame
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=fa4376d28e19b0835f948c5b42f13738f68bd9a1;p=openwrt%2Fstaging%2Fblogic.git

[media] gspca: reset image_len to 0 on LAST_PACKET when discarding frame

Reset image and image_len to NULL/0 on LAST_PACKET when we're in discard
frame mode, just like we do when not discarding the current frame.

The new se401 driver uses image_len for SOF/EOF detection and thus depends on
this.
