From 2e668962a54b64f3daffb8eef3ca538e25324d1a Mon Sep 17 00:00:00 2001 From: Ian Armstrong Date: Sat, 11 Oct 2008 06:39:05 -0300 Subject: V4L/DVB (9190): ivtv: yuv write() error handling tweak Modifies behaviour of a failed dma write() operation for the yuv device. If the dma transfer for the yuv device fails, the write() operation will now exit immediately.

(Neither poll nor read may be called unless a call to open succeeds. A successful call to open will always set the file private_data pointer. Verifying that it is not null is therefore unnecessary. The associated release and mmap calls currently ignore this check.) 3) adds a space to syslog output. 4) removes an unused function prototype.
