From: Sakari Ailus Date: Tue, 13 Oct 2020 12:12:02 +0000 (+0200) Subject: media: ipu3-cio2: Check receved the size against payload size, not buffer size X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=98f9aafa9f411bbc4f352191340b74db0ba908a8;p=linux.git media: ipu3-cio2: Check receved the size against payload size, not buffer size Compare the received size of the payload size, not the allocated size of the buffer that is page aligned. This way also images that aren't aligned to page size are not warned about. Also wrap a line over 80 characters.
