Hans Verkuil e2fc6edd37 media: videobuf2: revert "get_userptr: buffers are always writable" ... Commit 707947247e ("media: videobuf2-vmalloc: get_userptr: buffers are always writable") caused problems in a corner case (passing read-only shmem memory as a userptr). So revert this patch. The original problem for which that commit was originally made is something that I could not reproduce after reverting it. So just go back to the way it was for many years, and if problems arise in the future, then another approach should be taken to resolve it. This patch is based on a patch from Hirokazu.
