[PATCH][next] video: fbdev: atmel_lcdfb: remove redundant initialization to variable ret

[Colin King]

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

Currently variable ret is being initialized with -ENOENT however that
value is never read and ret is being re-assigned later on. Hence this
assignment is redundant and can be removed.
