    SubjectRe: [PATCH] leds: lm3697: Fix out-of-bound access
    Hi!

    > Signed-off-by: Ultracoolguy <ultracoolguy@tutanota.com>

    I'll need your real name to apply a patch.

    > Hi, all. This is a patch fixing an out-of-bounds error due to lm3697_init expecting the device tree to use both control banks.  This fixes it by adding a new variable that will hold the number of used banks.

    Ok, so I assume this is only problem with certain device trees, and
    not a problem with dts' in mainline?

    This is not trivial patch, no need to cc trivial tree. OTOH Ccing
    Marek who did a lot of cleanups in -next might be useful. Doing that
    now.

    Best regards,

    Pavel
