Subject: [PATCH] [media] drivers/media/pci/zoran: remove redundant assignment to pointer h

From: Colin Ian King <colin.king@...onical.com>

The pointer h is already initialized to codeclist_top so the second
identical assignment is redundant and can be removed. Cleans up clang
warning:

drivers/media/pci/zoran/videocodec.c:322:21: warning: Value stored to 'h'
during its initialization is never read
