From 08340d0b0c4b007c6ea1f300e3281b012da7f21b Mon Sep 17 00:00:00 2001 From: Trent Piepho Date: Sat, 28 Mar 2009 18:25:36 -0700 Subject: stkwebcam: Remove buffer type check from g_parm and q/dq/reqbufs From: Trent Piepho The v4l2-ioctl core only allows buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined to be used with vidioc_(q|dq|query)bufs(), vidioc_reqbufs() and now vidioc_(s|g)_parm. This driver only defines ->vidioc_try_fmt_vid_cap() so only VIDEO_CAPTURE buffers are allowed to be used with vidioc_g_parm(), vidioc_qbuf(), vidioc_dqbuf(), and vidioc_reqbufs().
