V4L/DVB (6350): V4L: possible leak in em28xx_init_isoc
Coverity (CID 1929) spotted the following: if a transfer buffer allocation fails, the last allocated urb is leaked (it hasn't been stored in dev->urb[] yet so em28xx_uninit_isoc misses it). The patch also includes a small typo fix. Signed-off-by: Florin Malita <fmalita@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
