Henry Martin 1be2000b70 backlight: pm8941: Add NULL check in wled_configure() ...

[ Upstream commit e12d3e1624 ]

devm_kasprintf() returns NULL when memory allocation fails. Currently,
wled_configure() does not check for this case, which results in a NULL
pointer dereference.

Add NULL check after devm_kasprintf() to prevent this issue.
