Subject: [PATCH] drm/framebuffer: break out of loop, if the requested element is found
Date: Sun, 16 Oct 2022 16:03:23 -0400 [thread overview]
Message-ID: <20221016200324.17930-1-someguy@effective-light.com> (raw)
We can stop searching through the linked-list after we have found the
element we are looking for. So, break out of list_for_each_entry()
after we have found the element we are looking for in drm_mode_rmfb().
