From: Vincent McIntyre To: linux-media Content-Type: text/plain; charset="UTF-8" Status: RO Content-Length: 2188 Lines: 73 I find it helpful to be able to build the linux-media modules for a kernel other than the one I am currently running. This is a resend of the patch that appeared at https://patchwork.linuxtv.org/patch/59979/ and completely supercedes that patch. There are no differences in the patch, just the formatting of the submission email.
