Description henry 2025-03-28 07:33:26 UTC 
vedio: backlight: Add NULL check in wled_configure
    
    devm_kasprintf() can return a NULL pointer on failure,but this wled->name
    returned value in wled_configure is not checked.
    Add NULL check in wled_configure, to handle kernel NULL
    pointer dereference error. This is similar to the commit 050b23d081da.
