[PATCH] backlight: ili922x: remove redundant variable len

[Colin King]

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

The variable len is assigned but never read, therefore it is redundant
and can be removed. Cleans up clang warning:

drivers/video/backlight/ili922x.c:276:2: warning: Value stored to 'len'
is never read
