From dab7e3106ddd6cbc3b55301228407b9d17ce7773 Mon Sep 17 00:00:00 2001 From: Andreas Bombe Date: Sun, 21 Mar 2010 16:02:45 -0300 Subject: V4L/DVB: V4L2: Replace loops for finding max buffers in VIDIOC_REQBUFS callbacks Due to obvious copy and paste coding a number of video capture drivers which implement a limit on the buffer memory decremented the user supplied buffer count in a while loop until it reaches an acceptable value. This is a silly thing to do when the maximum value can be directly computed.
